altrix®

Strong combination

 

altrix® multilayer roll-bonded clad plates manufactured by means of the in-house-developed cladding-by-rolling method as two-ply or three-ply plates. The base material features high degrees of toughness and good weldability. The coating material features highest strength and wear resistance in hardened condition.

 

Areas of application

 

Multi-layer altrix® plates are typically used in applications such as suction dredger tubes, ridge forming plates, wear plates on roll housings and in mold engineering, paddles in log washers, slides, chutes and transfer plates in the sand, gravel and concrete industry.

 

Materials

 

The standard base material of altrix® multilayer plates is steel grade S235 pursuant to EN 10025-2. The coating material used is 2842 (altrix 90). In hardened condition, a hardness of up to 66 HRC can be achieved. altrix® plates are delivered in as-rolled condition.

 

Dimensions

 

  • Sheet thickness: 7–80 mm 
  • Maximum sheet width 3,800 mm 
  • Maximum plate length 12,000 mm 
  • Ordered weight: at least 10 tons per line item 
  • Maximum unit weight 6.3 tons per single plate 

The correct coating thickness distribution must be determined while taking into account the desired wear resistance and resistance to failure. A thickness ratio of 50/50 between the cladding and the base material is typical for two-layer plates, and a ratio of 33/34/33 (hard/tough/hard) for three-layer plates.

 

Advantages of altrix® 

  • Longer service life due to 
  • high hardness and resistance to failure of the coated metal 
  •  Smooth surface: good flow behavior, little zinc build-up 
  •  Best weldability in as-delivered and hardened condition 
  •  Simple fastening procedures

High-strength plates

High-strength heavy plates made by voestalpine of fine-grained steels can have a minimum yield strength of up to 700 MPa. The special ultra-high-strength grades achieve a yield strength of up to 1100 MPa.

Show more

High-strength plates

Higher stress

Machines and buildings are becoming bigger and bigger. When the size of a component is doubled in length, width and height, the weight increases by a factor of 8, while the load-bearing cross-sectional surface area only increases by a factor of 4. This increases the stress, or the weight in relation to the cross-sectional surface area, by a factor of two. High-strength steels can absorb these higher stresses, even when the component weight is reduced.

Concrete advantages

The lower weight of high-strength and ultra-high-strength heavy plates saves costs: Input material quantities, transport costs, assembly and foundation costs are reduced substantially. Costs are also saved during further processing. Thanks to favorable weldability, work can be completed more quickly and efficiently. Significantly reduced quantities of welding consumables are required, and weld seam testing is made easier.

Our program

High-strength heavy plates are available as fine-grained steels with a minimum yield strength of 620 and 700 MPa. Ultra-high-strength heavy plates are available as voestalpine special grades at 900, 960 and 1100 MPa.

Machinery Industry

Made for the toughest tasks

Some industries are what steel was made for. The world of machinery is one of them. Steel made by voestalpine is perfectly within its comfort zone where highest mechanical loads and high-tech materials come together in highly sophisticated designs. Technical limits are constantly being pushed upward by further developments and innovations. Best processability and increasingly demanding mechanical properties lead to complex designs that leave nothing to be desired in terms of performance and efficiency. Steel can be used in the most diverse applications. Wear resistance, ultra-high strengths and high quality in any case.

Exploring new frontiers

What would our daily life be like without machines? Very different, that's for sure. The invention of effective new tools has always been a way of overcoming our limitations, and we are still creating innovative materials to push the limits even further. At voestalpine, we have proven this again and again with new and optimized products. Expertise from a wide range of highly innovative industries is bundled and engineered into materials and solutions for machinery, equipment and vehicles. The solutions are not only convincing in the lab, and they open new possibilities by increasing efficiency in design, production and use.

Consistently reduced weight

When high strength is no longer sufficient. With alform®, voestalpine offers an ultra-high-strength material to be used in combination with the alform® welding system to produce ultra-high-strength weld joints. A reduction in material thickness of more than 70% without compromising any performance results in a weight savings that goes hand in hand with substantially increased efficiency. Best cutability, best forming behavior and excellent toughness round off this power package.

Safely increased efficiency

The demands on the materials used in modern engineering are enormous. Perfect workability during the production process must not be a contradiction to maximum wear resistance and economy of use. With durostat®, voestalpine has succeeded in more than just meeting these requirements. One of the safest, most robust and efficient materials, durostat® boasts of highest durability in abrasive applications, enormous weight savings when compared to conventional structural steels, hardness second to none thanks to a specially developed direct hardening process, best cold formability thanks to fine-grained microstructure and high degree of purity, and best weldability thanks to the optimized carbon equivalent.

The skipster is the true winner in lightness and stability.

alform® makes many things lighter. The thermomechanically rolled (TM) material combines lightness with stability like no other, making it the perfect candidate for countless applications where high load capacity and low weight are essential. This applies to high-tech and complex machinery as well as comparatively simple containers.

TransANT railway freight cars made of high-strength alform® steel

Rail Cargo Group (RCG) was looking for a lightweight design that would meet the logistics requirements of the 21st century. The subsidiary of ÖBB has many years of valuable experience in freight transports and is part of a very strong international network. Coupled with the material expertise of voestalpine, a future-oriented design has now been developed with TransANT. This could be a revolution in railway freight car design.
