Corus and Salzgitter have claimed that automotive chassis and crash structures will benefit from mass reduction and improved impact resistance from their new jointly developed of 'high strength and ductility' (HSD) steels.

The steels have a high manganese content and are intended for use in the automotive industry.

The two firms claims the performance of HSD steels is superior to conventional steels, with strength levels of 600 to 1400 Mpa corresponding with elongations of 70 to 20%, respectively.

Both companies will continue to collaborate on research and development.

The various HSD steel grades have been developed for a variety of applications, in particular for parts with complex geometrical structure combined with high strength requirements, such as sophisticated components for mechanical engineering applications.

The makers claims the automotive industry will achieve substantial benefits from mass reduction, improved crash resistance and enhanced design freedom.
