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.

We are not talking about autumn or the rain, but we are thinking about our weather-resistant TM steel grades.

Weather-resistant structural steels acc. to EN 10025-5

The new edition of EN 10025-5 in 2019 finally included thermomechanically-rolled (TMCP) weathering steels in the European standard.

The TMCP steel grades S355J2W+M, S420J2W+M and S460J2W+M stand out due to their low carbon content and significantly higher toughness, even at low temperatures. This guarantees best workability and weldability.

Heavy plates made of thermomechanically rolled fine-grained structural steel.

alform® steels are thermomechanically rolled fine-grained structural steels with excellent weldability, toughness and cold-forming behavior, which makes them extremely versatile.

Heavy plates made of thermomechanically rolled fine-grained structural steel.

We supply standard and high-strength, thermomechanically rolled, fine-grained steels of the highest quality with minimum yield strengths ranging from 355 355 MPa to 700 MPa.

As a special grade of voestalpine steel, alform® is primarily used in applications such as steel structures, bridges, pressure pipes, vehicles and cranes.

Our thermomechanically rolled fine-grained steels are characterized by a high degree of toughness and excellent weldability. The low degree of cold cracking and high degree of toughness in the welding seam result in the highest safety standards in welded structures.

Utilization of the higher yield strength of high-strength fine-grained steels (alform plate 420 M, 460M, 500 M and 550 M) as opposed to conventional structural steels results in lower cross-sections. This leads to cost savings in lower component weights and reduced expenditures for transports, assembly and foundations as well as savings in component manufacturing, especially during welding.

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.

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.

Wear-resistant heavy plates

Parts used in abrasive environments wear out quickly. In order to lengthen the service life of such components, we have developed two special steel grades whose service life is significantly longer than conventional steels. Our online-hardened durostat® carbon steels are especially wear-resistant and demonstrate the best processing properties. Our highly wear-resistant altrix® steels include roll-clad multi-layer plates for an even longer service life.
