Waiting has an end!

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.

To highlight the advantages of our weather-resistant TM steel grades please find below a comparison of normative requirements and typical voestalpine values of CEV:

S355J2W / S420J2W / S460J2W	max. CEV acc. Norm EN 10025-5	0,52%
S355J2W+M / S420J2W+M / S460J2W+M	typical voestalpine values at wt=50mm	0,41%

Cost saving when corrosion coating not applied
No maintenance required (re-application of corrosion coating)
Weatherproof steel achieved by addition of phosphorus, copper, nickel, chromium or molybdenum
Alloys form a dense oxide layer that retards corrosion
Applications in steel structures, bridges and vehicles

We supply higher strength & lighter weight

alform® heavy plates find their applications wherever high workability and weldability coupled with high strength and weight savings are in demand. Utilization of the higher yield strength of high-strength fine-grained steels as opposed to conventional structural steels results in lower cross-sections. This leads on the one hand to cost savings in lower component weights as well as reduced expenditures for transports, assembly, foundations, component manufacturing, especially in welding as a result of minimized seam cross-sections.

Elimination of paint coating and maintenance

The alloying of small amounts of phosphorus, copper, nickel, chromium or molybdenum leads to the formation of a protective layer on weather-resistant steel outdoors. This layer protects the steel from further corrosion. Weather-resistant structural steels thus provide cost advantages as no anti-corrosion coating or maintenance required of the protective coating is required.

Machinery Industry

The products of voestalpine feature excellent processing properties and provide optimized solutions for the machinery industry.

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.
