  • Metallic coated - Advanced high-strength steel

    We offer dual-phase and complex-phase steels. Dual-phase steels combine high yield strength with good ductility – ensuring excellent fatigue properties and energy absorption. Complex-phase steels provide good bendability and edge ductility, enabling the cold forming of simple-shaped components.

    Metallic coated - advanced high-strength steel

    Our ultra-high strength steel grades for automotive applications, such as HyperForm®, are lightweight and offer design freedom for complex parts. Their high yield and ductility ensure shape accuracy and tolerancing, which enable maintained in-service performance for difficult-to-form parts.
