For new standards in the machinery industry.
Our durostat® steel grades set new standards with their highest quality and withstand the greatest stresses. They offer a wide variety of mechanical properties and stand for highest-quality processing. These steels can also decisively prolong the service life of your products and significantly reduce their weight.
Longer service life
We developed the durostat® product range in order to prolong the service life of your components in abrasive environments. Our steel grades have a significantly longer service life than conventional steels and withstand the most stringent environments.
When compared to conventional construction steels, sheet thicknesses can be significantly reduced while maintaining the same length of service life. This leads to lower dead weights and higher payloads, especially in automotive engineering.
High degree of hardness
Their high level of hardness is adjusted by means of accelerated cooling after hot rolling (direct hardening) or through conventional quenching. We prefer direct hardening because this method improves toughness and reduces scale formation.
Very good cold formability
Our durostat® steel grades are very well suited to cold forming, independently of whether the steel is direct-hardened or non-hardened. This is achieved through a homogeneous, fine-grained structure as well as a high degree of purity.
Our modern alloying strategies with optimized carbon equivalents guarantee good weldability, a factor that especially applies to direct-hardened durostat® steels. Preheating can be completely eliminated for lower sheet thicknesses.
The outstanding flatness is achieved through precisely controlled rolling processes in combination with modern leveling units. This is highly advantageous during cutting and further processing and achieves optimized dimensional accuracy of the manufactured components.
A uniform layer of scale forms on the sheet surface following hot rolling in our process route. The natural protective layer acts against corrosion during transport and can easily be removed through sand blasting. Selected dimensions can be supplied with a pickled surface, which makes it possible to forego descaling prior to coating.
