Hardox at work

  • Hardox knives cut costs and time

    Efficiency in the Mexican Ingenio de Atencingo sugar plant has been boosted thanks to its new process knives made from Hardox 500, a wear resistant steel produced by SSAB.

    THE CHALLENGE

    When shortening the tough sugar cane before it is mashed in a huge mill, the sugar plant's knives must both slice through the fiber-rich cane stalk and resist the acid-like sugar juice.

    THE SOLUTION

    Ingenio de Atencingo switched its knife steel to Hardox 500, making its knife blades last three times as long as the ones before.

    "The Hardox steel in the knives helps us to slash maintenance time," says Plant Manager Metrobio Garcia. "Being able to avoid unnecessary downtime is really vital for us. Not only are the blades lasting longer, but the end result is better, too."

    “The knife blades last three times as long”

    CUSTOMER BENEFITS

    Reduced downtime also cuts personnel costs, an important part of the company's efficiency program that has been intensified due to the economic crisis. The company is now looking into letting SSAB study other stages of the refining process, including its harvesting machines.

  • Intermix builds the world’s first Hardox concrete mixer

    At the beginning of the year (2012), the German concrete mixer manufacturer Intermix launched a lightweight concrete mixer with both the concrete drum and the inner spiral made out of 3-millimeter Hardox steel plate. The new mixer already makes up 60 percent of the company’s sales.

    “Compared to the 4.5 millimeter standard steel that we used before, the lightweight version reduces the weight of the structure by as much as 18 percent,” says Harald Schmidt, sales director at Intermix. “The most important part is that Hardox is so wear-resistant that the lifetime of the concrete mixer stays the same even with reduced steel thickness.” 

    Intermix is one of Europe’s leading manufacturers of concrete mixers. It wanted to optimize the payload of its vehicles as concrete is heavy at 2.4 tons per cubic meter. German road regulations allow a maximum total weight of 32 tons, while an average four-axle concrete mixer weighs about 14 tons empty.

    Hardox constructions have been around for a while in the field of dump trucks, but there had not been any attempts to use it in a light concrete mixer. Intermix teamed up with SSAB to learn how to work with the thinner, highly wear-resistant Hardox plates. On January 16, 2012, the company received its “Hardox in My Body” (HIMB) license.  

     “We are proud to be the first on the world market with an HIMB concrete mixer,” says Schmidt. “Considering the huge interest we’re seeing in Germany and other countries, we expect it to sell well in a large part of the European market in the near future.”

  • Antech joins “Hardox in My Body”

    After two years of using Hardox in its applications, Antech Attachments Co. Ltd has now joined SSAB’s “Hardox in My Body” program. The company, a leading Taiwanese manufacturer of high quality excavator teeth, buckets and attachments, relies on the high quality performance of Hardox to gain a competitive advantage.

    The challenge

    As a manufacturer of earthmoving attachments for the global construction and mining equipment markets, Antech Attachments must ensure that its products can stand up to tough working conditions.

    "Before we used Hardox in our excavator buckets, we were constantly battling with bent cutting edges and bucket floors due to the lower tensile strength of the steel we used," says Henry Liao, Antech Attachments' Company Director. "Cracks around the wear lining were common due to its poor weldability and low impact toughness."

    As a result, the company was forced to build its buckets with heavier gauge steel in order to maintain bucket life, which made the buckets heavier and more costly to make.

    “We reduced overall bucket weight by 20-25 percent”

    The solution

    By applying Hardox wear plate in its products, the company was able to cut down bucket weight by as much as 30 percent, while maintaining the same or better wear life. "Hardox's superior wear performance, good weldability and formability allows us to produce high performing attachments and keeps us ahead of our competition," says Liao.

    As the company gained success by applying Hardox in its products, many of its competitors also adopted similar types of wear resistant steel from various sources. "Though they all claim to be quenched and tempered wear steel, we believe the quality does vary," Liao says.

    "We believe by joining the 'Hardox in My Body' program, it will improve our product image by spreading a clear message to our clients that we are using high quality wear resistant steel to ensure long product life and performance," Liao explains.

    Customer benefits

    “In a typical 60-ton-class excavator working in a rock quarrying operation, we were able to reduce overall bucket weight by around 20-25 percent, while at the same time extending the bucket usable life by 50 percent," says Liao.

  • HiTuf boosts car shredder’s bottom line

    The Australian company Pacific Shredder designs and builds steel shredding machines that can shred a car into scrap in seconds. They rely on Hardox HiTuf to keep their shredders working when those made of softer material fail.

    The challenge

    Pacific Shredder, located in Newcastle, New South Wales, was looking for a steel that was stronger and lasted longer. Normal steel is prone to cracking and wear, and has to be replaced often.

    "A car shredder is basically a 60-ton drum made of eleven rotor disks, with twelve or sixteen manganese hammers attached to it," says Joe Beentjes, owner of the company. "The rotor rotates at 500 rpm and the hammers smash the car against a series of anvils, breaker bars and grids. The inside is armored with wear plates that stop the flying metal from simply eroding the whole structure."

    In a business where a breakdown doesn't just mean loss of productivity, it means bringing in a 200-ton crane to lift the rotor out and repair it, durability is everything. 

    The solution

    "Steel recycling is all about dollar-cost per ton," says Beentjes. "The cost of scrap and the price for recycled steel are pretty much fixed, so one of the only ways to boost the bottom line is by improving the life of the shredder. This is why we use Hardox HiTuf steel for our components."

    "SSAB's technical knowledge and expertise is fantastic. Whether it's machining, welding, cutting, they make sure we understand everything we need to know about pre-heat, post-heat, welding wire types, and so on.

    “SSAB’s steel is the best we’ve ever used”

    Customer benefits

    “We build quality-engineered machines,” says Beentjes, “and a quality product like Hardox HiTuf certainly enhances our reputation. SSAB’s steel is the best we’ve ever used for these components, for a number of reasons. First, it’s simply the best high-tensile wear-resistant plate in the world. The stuff from the competition just doesn’t have the through-hardness that you need in a shredder.”

    “Secondly, SSAB is the only manufacturer that produces this sort of highly resistant plate in the 100mm and 120mm thicknesses we need. This is critical to our designs because the extra thickness and extra toughness gives our shredders much longer life. Our wear plates and rotor disks keep on going when others have turned into scrap themselves.”

  • Thinner plate for more efficient refuse collection trucks

    The strength and durability of Hardox enable the Labrie Environmental Group to use much thinner plate for their vehicle bodies. This results in lighter vehicles that can thereby carry heavier payloads and use less fuel.

    THE CHALLENGE

    To build lighter and stronger bodies

    The Labrie Environmental Group manufactures some of the best equipment on the market for the waste and recycling industries. The company was founded in 1933 and made a name for itself in the refuse industry in 1971 when it launched the Top Select refuse collection truck for collecting directly from the roadside. More than 3000 Top Select vehicles are now in operation and Labrie has grown into the third largest North American manufacturer of equipment for waste management. The vehicles are sold through 50-odd distributors under the Leach, Labrie and Wittke brand names.

    These are some of the technically most highly advanced refuse collection vehicles on the market. They are comfortable, ergonomic and productive and have a high collection rate without damaging the carts, bins or containers, says Loic Marchand, the company’s Marketing Director.

    Labrie continually strives towards building lighter, stronger and more durable vehicles. This is where SSAB Hardox steels play a major role.

    THE SOLUTION

    Hardox yielded all in one

    Noha Mandour, the Group Communications Director at Labrie, says:
    The refuse emptied into the truck body causes wear of the floor plates. When we were using other steels, we had to change parts and carry out maintenance work more often. A customer who operates 60–70 vehicles will cut the maintenance costs substantially if we use Hardox.

    But there are other benefits too:
    Lighter bodies also enable higher payloads to be carried within the legal stipulations, and ensure more efficient operation, since the durability of SSAB steels also contributes to raising the quality of the vehicles.

    Hardox also enables Labrie to use whole plates in the side walls of the bodies.

    Compared to two or three plates that are welded together, a single Hardox plate is both stronger and more resistant to corrosion, since there are no welded joints. One Hardox plate also looks better, since customers have a much larger flat surface that can be used for advertising and pictures, declares Noha Mandour.

    BENEFITS TO CUSTOMERS

    Lower operating and maintenance costs

    The strength and durability of Hardox enable us to use much thinner plate for our vehicle bodies. This reduces the vehicle weight and thus cuts the fuel consumption – which is important, bearing in mind that most refuse collection trucks start and stop about every 15 seconds, says Loic Marchand, and continues.

    For the operators, the higher investment cost is counterbalanced by the long-term savings due to the lower maintenance and operating costs.

    “Lighter refuse collection trucks use less fuel”

  • Hardox increases payload of new waste disposal trucks

    When SITA Deutschland GmbH wanted 12 new state-of-the-art waste disposal trucks, with specially developed containers, it relied on the partnership of Becker Machine Construction and Containerbau Hameln for high quality and on-time delivery.

    Containerbau Hameln, which produced the containers for the new trucks, has been a partner of Becker Machine Construction for 27 years and is an official member of SSAB’s “Hardox in My Body” program.

    “Thanks to Hardox, no braces were necessary to stabilize the containers,” explains Volker Greiner, associate of Containerbau Hameln. “Instead there is a depression on the sides, which keeps the containers from extending or deforming.”

    Because of the light but strong Hardox plates, it was possible to construct the sides using 3.2 mm Hardox and the floor in 4.0 mm. The effect: the containers are a ton lighter and the truck with trailer can take up to two tons more load. This is a gain of 20 percent more payload.

    “We’re pleased once again to have proved the outstanding quality of Hardox,” says Jens Fehling, regional sales manager at SSAB.

    In addition, the containers have a moveable inner wall, which makes it possible when collecting glass, for example, to separate the glass by color in two different compartments. This saves gas and time.

    At the delivery of the trucks in Hassfurt, Germany, on December 16, SITA representative Gerd Baumann praised the commitment of all the parties involved.

    “Quality requires reliability, and reliability has a price,” says Baumann. “But thanks to their advantages as opposed to cheaper alternatives, these high-quality trucks save costs through higher work efficiency and a longer lifespan.”

    Jürgen Mielke, CEO of Becker Machine Construction, is also very pleased. “Thanks to its partners’ commitment and ideas, SITA has achieved an innovative and unique solution which is tailor-made for its use in waste disposal,” he says.

  • Hardox Wear Plate Improves Russian Refuse Trucks

    MosKomMash, a Russian producer of trucks used for refuse collection, now uses Hardox 450 to make its truck tails. The upgrade dramatically improves the quality of the tails, which last longer and cut costs.

    THE CHALLENGE

    Previous steel needed reinforcements

    A regular MosKomMash refuse truck had an 8-mm thick tail produced from mild steel with reinforcements on the bottom. When the economic climate changed, the company sought greater efficiency in its production and construction materials.

    “During the boom days, we never thought twice about Hardox as we focused more on mass production than on innovations, even though product improvement was always important for us,” says Chief Designer Alexander Melnik. “We’d heard about Hardox, but it was only during the downturn when SSAB’s Moscow representative visited us that we decided to test Hardox in our refuse trucks.”

    THE SOLUTION

    Hardox 450 thinner yet stronger

    The 8-mm thick tail was replaced in two test trucks with 5-mm thick Hardox 450 without reinforcements. The results, Melnik says, exceeded all his expectations. The tail made of Hardox 450 lasted three times longer than the normal tail made from mild steel, and weight and production costs were reduced since less welding was needed. The company also received welding recommendations from SSAB.

    “Hardox 450 lasted three times longer”

    CUSTOMER BENEFITS

    Improved quality and reliability

    “It costs around USD 117 more to replace the mild steel with Hardox but I have to say that this is really nothing compared to the benefits that we, and end users, get,” Melnik says. Besides being the first company in Russia to use Hardox for this type of application, he firmly believes that it will dramatically improve the quality and reliability of MosKomMash’s trucks.

  • Una vida útil más larga para una carga más ligera

    La mina de cobre de Dexing, una de las mayores minas a cielo abierto de este mineral en Asia, deseaba encontrar una chapa antidesgaste más sostenible para el revestimiento de sus tolvas, un elemento fundamental para su sistema de extracción de mena. Tras ensayar distintas marcas, el Hardox 550/600 de SSAB se erigió como la opción más obvia.

    EL RETO

    Antes de la implementación de Hardox, las chapas de revestimiento de las tolvas se desgastaban rápidamente en las operaciones diarias con un alto grado de exigencia. El frecuente cambio de las chapas aumentaba la carga de trabajo y las paradas operativas, al requerir esto dos semanas, amén de ocasionar diversas dificultades en el mantenimiento.

    “La abrasión del sistema de extracción de mineral nos ha preocupado durante mucho tiempo”, sentencia Huang Chuanlu, jefe de equipamiento de la sección de transportes ferroviarios de Dexing.

    LA SOLUTIÓN

    El año pasado Dexing aplicó Hardox 550 y 600 en los laterales y fondo de sus 18 máquinas de extracción de mineral, obteniendo unos resultados espectaculares.
    “La vida útil de la chapa de revestimiento puede multiplicarse por dos e incluso tres”, indica Huang. “Ello recorta la frecuencia del mantenimiento y nos ayuda a alcanzar nuestro objetivo de reemplazar la chapa cada dos años. Además, reduce la carga sobre el motor, puesto que la delgadez de la chapa antidesgaste Hardox aligera considerablemente la tolva.”

    "Al confiar en Hardox, las paradas operativas del sistema se han reducido a la mitad, aumentándose la producción. Ello garantiza la sostenibilidad de las operaciones y mejora considerablemente nuestro volumen de negocios. Seguiremos colaborando con SSAB para cambiar también el resto de sistemas."

  • SSAB steel builds better container

    Container manufacturer Ellermann wanted to make containers in the same size as before but with more load capacity. Thanks to SSAB’s high strength steel their vision has become reality.

    The challenge

    The German company previously used aluminum to make its containers, but needed a material that was stronger and lighter.

    The solution

    Ellermann now uses wear steel from SSAB for the floor and sidewalls of its containers. This has increased the load space from forty cubic meters to forty-two. A further bonus is that the containers are now substantially lighter, which delivers weight benefits.

    “Thanks to the new design we can take an extra 1.5 tons weight per container and 3 tons on a 20-ton load. That represents a 15 percent increase in load capacity,” says Tobias Ellermann, president of Ellermann GmbH.

    “The containers are now substantially lighter”

    Customer benefits

    In addition to increased load space, the new containers are also much stronger than the old ones. The stabilizing support beams that once were placed around a container are no longer needed because the material is sufficiently strong in itself.

  • Hardox 500 gives Hefei Cement Research & Design Institute's machines a longer life-span

    In the province capital Hefei of Anhui Province, interesting things are going on. At Hefei Cement Research & Design Institute (HCR&DI) the engineers started to use Hardox wear plate inside their roller presses and separators for the cement industry in 2005. Since starting using Hardox 500, the roller presses and separators from HCR&DI are more wear resistant, lighter and have a much longer life-span.

    SSAB’s famous Hardox wear plate is a versatile abrasion resistant steel plate that increases payload and service life in tough environments. Hardox has a combination of strength, hardness and toughness which makes it stand up to extreme wear. And the workshop friendliness cuts production costs.

    - When manufacturing roller presses and separators, we are looking to make the process as simple and cost conscious as possible, says Mr. Zhang Yonglong, the General Manager of Mill Engineering Co., Ltd. But we must not compromise with our high quality. Before using Hardox wear plate in our products, we constantly suffered from problems with maintenance and the difficulties that occurred when we had to replace the plate.

    In cement production, the products from HCR&DI play an important role. A roller press crushes cement clinker prior to the material being sent to the cement mills for finish grinding. The separator separates fine particles from coarse particles. The fine particles are collected, while the coarse particles are being sent back for further grinding.

    - We started to study SSAB’s products in 2002, says Mr. Yonglong. Our engineers went on an international fact-finding mission to study manufacturers abroad. And after extensive testing we decided to use Hardox 500 in 2005. We were very pleased with the result.

    In the early days HCR&DI used their own wear resistant surfacing material and put a wear layer on top of the ordinary steel plate. That process turned out to be a waste of time and the result did not meet HCR&DI’s high standards. Using Hardox 500 resulted in a more wear resistant plate and a decrease in maintenance hours, resulting in the machines having a longer life-span.

    - The persons at SSAB are not your average talent, says Mr. Yonglong. Our engineers have an on-going dialogue with the people at SSAB. They speak over the phone several times a month and meet face-to-face when is needed. We are open to try new products. We are already thinking of trying Hardox 600 for some parts in our machines.

    At HCR&DI sales has increased from 120 Million yuan in 2005 to 1.6 Billion yuan in 2009. The company has become a famous and well-renowned brand in China; the workers constantly need to put in over-time to cope with the increasing demand. The engineers have focused on cutting cost, simplicity in maintenance, a longer life-span and reduction of pollution and noise. But Mr. Yonglong is not satisfied just yet; he has high ambitions.

    - Today our equipment has the production capacity of 5000 tonnes cement per day, and we are working on the new equipment which will have the capacity of 10 000 tonnes per day, he continues. With our close relationship with SSAB, we believe this is just a matter of time.

  • Hardox helps VERCO supplying equipment for extreme mining

    Using Hardox and Weldox in as much of its excavation equipment as possible has high priority at VERCO, now that the company is expanding into the segment of extreme mining equipment.

    THE CHALLENGE

    Minimize maintenance costs

    By giving priority to product quality, VERCO has succeeded in retaining its position as one of the leading Italian suppliers of wear parts for mining and quarrying machines. The company specializes in buckets for mining excavators and wheeled loaders, up to 30 m³ of capacity, and in liners for crushers and recycling equipment. . VERCO was one of the first companies in Italy to build excavator buckets entirely of Hardox wear plate.

    According to Daniele Arrighi, Export Manager at VERCO, a great challenge is to minimize maintenance costs in these applications. VERCO customers are dependent on the company being able to deliver not only superior products, but also technical expertise.

    "We have a good distributor network in Italy and abroad, and are now penetrating new markets and new segments. So we must be prepared to tackle new technical issues. Our objective for the future is to introduce SSAB and VERCO products to as many companies as possible," says Arrighi.

    "We offer durable wear parts with low maintenance requirements, which reduces the number of stoppages. Our customers are buying from us equipment which can mounted on excavators of 300-400 tons of operating weight. Stoppages of such machines are extremely expensive. With our help, they can improve the reliability and the cost-efficiency of their enormous equipment. "

    "We offer durable wear parts with low maintenance requirements, which reduces the number of stoppages."

    THE SOLUTION

    Membership gives access

    As member of Hardox In My Body and Hardox Wearparts, VERCO has access to SSAB technical expertise and can thus offer its customers the latest applications for Hardox and Weldox.

    “We offer durable wear parts with low maintenance requirements, which reduces the number of stoppages and cuts costs. We have a strong, long-term relationship with SSAB representatives and can always rely on technical support from them whenever we need it. We use Hardox 400, 450 and 500, Hi-tuf and also Weldox 700 for excavator buckets used at very low temperatures,” says Arrighi.

    CUSTOMER BENEFITS

    Higher productivity at lower costs

    SSAB also assists VERCO  customers with design support.

    ”When customers face problems in their plants, we visit them together with an SSAB engineer who can offer advice on site, assess their technical requirements and assist in solving the problem – often by specifying a stronger steel. This type of cooperation benefits all parties,” says he.

    The high quality of SSAB steels makes it easy to design durable wear parts with the low maintenance requirements expected by customers.

    ”Our products provide customers with higher productivity at lower cost. In addition to raising the quality of the product, Hardox also provides other benefits, since the Hardox brand name itself is attractive to customers,” says Arrighi.

    “We say ‘Hardox’ and the customer hears ‘quality, reliability and long-term wear resistance’.  When facing the challenge of producing a bucket for a 400 tons excavator, it is impossible to offer an alternative between  “standard “ or “superior” quality. The quality of the material and of the welding must always be the best available!  Besides that, membership of Hardox Wearparts and Hardox In My Body provides Verco with benefits such as short delivery times, marketing support and information on new products.”

    “Hardox is the world’s strongest brand name in wear resistant steels – a powerful brand name – and we are proud to be able to tell our customers that our products are made of Hardox.”

  • Lighter body for more payload and better earnings

    Scepticism was the first reaction when the drivers at Longmei Engineering saw the thin bodies on the company’s new trucks. But after a few months, they were all convinced: Hardox is up to it.

    The challenge

    Reduction in cost per journey

    Longmei Engineering has around 100 trucks that yearly carry almost 12 million tonnes of excavated earth and rock from a coal-bearing seam at the Xiaolongtan coal mine in the Yunnan province of China. Every truck covers 100 000 kilometres a year, so a reduction in the cost per journey could produce substantial savings. According to Chen Hao, Plant Manager for Longmei, the company knew that they would improve the cost efficiency by redesigning the truck bodies.

    The solution

    Thinner and lighter Hardox plate

    SSAB technicians discussed the matter with engineers at Longmei, and showed examples of how thinner and lighter Hardox plate could be used for maximizing the payload capacity of the trucks.

    "We were willing to try something new. We had several meetings and discussions with SSAB, and their technical team showed us examples of truck bodies that were used in Europe. The bodies were very attractive, so we decided to run a trial with Hardox," recalls Chen.

    Scepticism was the first reaction when the bodies were delivered.

    "The truck body was a shock to us at first, and our drivers refused to believe that such thin plate could cope with more load. But after a few months of service, the drivers agreed that the new Hardox bodies were up to the task," he recalls.

    The whole of the company backed the decision to carry on with Hardox, and it was then decided to switch to a U-shaped body to lower the weight and increase the capacity further. The result was a success. Chen recalls that Hardox 450 enabled Longmei to reduce the body weight from 4.6 tonnes to 3.5 tonnes.

    "Since we haul earth and rock, the empty weight of the truck is of major importance to us," states Chen.

    "Many truck body manufacturers in China use mild steel with many reinforcements. But Hardox 450 needs no stiffeners, which is a major design benefit," says Sun Mangui, Design and Production Manager at Longmei.

    Customer benefits

    More load per trip = better profit margin

    Since Hardox bodies are lighter and thinner than those made of mild steel with reinforcements, the new Longmei U-shaped truck bodies can carry several tonnes more load per trip.

    "A Hardox body costs around eur 4 900 more to produce than a mild steel body. But a lighter truck can carry more load per trip, which results in a better profit margin. Every truck covers around 100 000 kilometres annually, so it takes only six months to recover our investment in Hardox."

  • A revolution in underground pipe laying

    Corazza, a leading Italian bucket and marble forklift manufacturer, was approached by one of its customers with a stability problem when laying pipes. Corazza and SSAB put their heads together and came up with an exciting innovation.

    THE CHALLENGE

    Stability for underground pipe laying

    Corazza is recognized for its quality, technical expertise, design flexibility and production response time.

    What makes Corazza stand out is its commitment to development. The company continuously works to ensure innovation in standards for buckets, fixed and rotating crushers, mini-excavators and sand timber grapple shears.

    This challenge arose from a customer seeking a solution to a stability problem – the chains that were being used to lift pipes were shaking and weaving.

    THE SOLUTION

    Speedy pipe

    Corazza worked with SSAB to come up with the Speedy Pipe. A rigid, and extremely strong, pipe replaced the chains, thus solving the problem of instability.

    The Speedy Pipe can be attached to excavators weighing 5 to 60 tons, with a loading capacity of between 1.5 to 8 tons. It is made from Hardox 400 which is extremely robust and durable.

    CUSTOMER BENEFITS

    Longer life span and higher productivity

    Due to the high quality of Hardox 400, Corazza’s Speedy Pipe pipe lifter is extremely strong with a long life cycle. It solves stability problems, offers maximum safety in the work area and eliminates the need for labour on the ground and in the dig. This means time spent on a job is reduced by 50% - a tangible benefit no other competitor is able to offer.

    Emanuele Loperfido, Sales Manager at Corazza, says “thanks to Hardox, our brand is known all over the world. If I had it my way, everything would be made from Hardox.”

    In the past five years Corazza’s purchase of Hardox has doubled. The entire Hardox product range is used for different applications and in thickness spanning from 6 to 100mm.

    Corazza

  • Joint tests of benefit to everyone

    The Bavarian Bergauer company and SSAB have long been running joint tests to arrive at solutions that would ensure a longer useful life – cooperation that benefits both parties.

    THE CHALLENGE

    To find solutions for a longer useful life

    Having been founded in 1961 for repairing track shoes for tracked vehicles, Bergauer broadened its portfolio to include the repair and maintenance of a wide range of other machine and wear parts. This includes the production and repair of excavator buckets, equipment for rock quarries, and wear parts for the recycling industry in the form of hammers and knives. Bearing in mind the aggressive wear to which the machine parts are subjected, the company always needs high quality steels in which high strength is combined with high impact strength. Bergauer specified Hardox for the first time in 1978 and has been a faithful customer ever since.

    THE SOLUTION

    Joint tests

    A series of joint tests on Hardox has strengthened the bond between the companies.

    The tests enable us to analyze wear-related problems. Both SSAB and we work towards finding solutions that extend the useful life which, in turn, translates into improved profitability for all concerned. Wear parts made of Hardox wear plate last longer, need less maintenance, and lower the total life cycle costs,says Robert Bergauer and recalls a recent example from a recycling company:

    After only six months of service in a shredder for binders, files and office paper, the 40 hammers were so deformed and partially destroyed that the machine no longer worked. This happened even though the manufacturer had sent a set of spare parts free of charge.

    The manufacturer blamed the breakdown on ‘foreign objects’. However, the problem was that the hammers with a hardness of around 320 HBW deformed and broke up when they struck the anvil, and the splinters flying around then accelerated the damage to the shredder.

    In consultation with SSAB, we suggested using Hardox 500 and 600. The machine has now been in operation for more than a month and the plant manager is pleased with both the speed at which we succeeded in solving the problem and with the competitive price we had quoted, says Robert Bergauer.

    “Valuable assistance on wear-related problems”

    BENEFITS TO CUSTOMERS

    Longer useful life and scope for finding new fields of operation

    Robert Bergauer is impressed by the direct and active contacts that he and his company have established with SSAB and its technical personnel.

    These contacts are particularly valuable when wear-related problems occur in a stone quarry or on a building worksite. This high quality technical support has often enabled us to manage difficult orders and discover new fields of operation.
