Overview of advanced high-strength steels

3rd generation of AHSS

In order to be involved in the design of the next generation of modern AHSS, thyssenkrupp Steel is cooperating closely in its development with Japanese steel producer JFE Steel Corporation. The result: the highly ductile grades jetQ^® 980 and jetQ^® 1180 for geometrically complex crash structures in vehicle bodies.

Dual-phase steel

The dual-phase steels DP-W^® and DP-K^® from thyssenkrupp are ideal for reducing weight and enhancing safety in modern cars.

Retained-austenite steel (TRIP steel)

Retained-austenite steels RA-K^® are modern, multi-phase steels which are characterized by the "TRIP'" effect when worked.

Complex-phase steel

Complex-phase steels CP-W^® and CP-K^® offer very high strengths and yield points.

Bainitic chassis steel

The hot-rolled bainitic chassis steel CH-W^® with optimized hole expansion is ideal for complex cold-formed chassis parts.

Ferritic-bainitic-phase steel

Hot-rolled ferritic-bainitic phase steels FB-W^® are modern, multi-phase steels which exhibit minimum tensile strengths of 450 and 580 MPa in the thermomechanically rolled state.

Martensitic-phase steel

Martensitic-phase steel MS-W^® is a modern, high-strength, hot-rolled multiphase steel which has a very tensile strength of 1,180 and 1,400 MPa in thermomechanically rolled condition.
