durostat®

Superior solutions 

Made of wear-resistant steel

Highest wear resistance and hardness for the highest stresses. Just like a diamond, our durostat® steels stand for highest hardness. This special property of our durostat® steels is the reason for their essentially higher resistance to wear than conventional steels. They are optimally suited to applications with high mechanical stress and high levels of abrasion. Our durostat® steels also guarantee excellent toughness at low application temperatures.

Chords

Supports and anchors

Offshore platforms stand on adjustable supports. During transport, the supports are retracted and protrude upwards. At the offshore site, they support the platform and anchor it to the seabed. Chords made by voestalpine Grobblech strengthen the gear racks of these supports and thus enable safe operation in adverse environments.

Complex manufacturing process

We developed our manufacturing technology for chords as hot-formed components in our in-house press shop. The pre-material is heavy plate made of high-strength and fine-grained structural steel produced in our own rolling mill. Strips are cut from this plate and formed into chords with a special tool on a hydraulic press with a maximum pressing force of up to 3500 tons. The tool function is based on finite element calculations and guarantees a high level of shape accuracy. After being hot-formed, the chords are water-tempered and straightened. Torch-cut or milled edging on the long and short sides is the final step in the production process.

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.
