Overview of advanced high-strength steels
Advanced high-strength steels are key to leveraging lightweighting potential in the automotive industry, particularly in the production of crash-relevant structural parts and complex-shaped components at reduced weight and cost.
By fine tuning the different microstructure constituents with their individual properties, the characteristic material properties of advanced high-strength steels can be controlled and optimized for the intended application. At thyssenkrupp we offer customers the ideal material for their requirements: from dual-phase, retained austenite and complex-phase steels to martensitic and ferritic-bainitic steels.
When it comes to further developing advanced high-strength steels thyssenkrupp takes a multi-dimensional approach, because alongside higher strength and weight-reduction potential, processing properties and a differentiated view of formability are key factors in adding value to our customers’ products.
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 steels CP-W® and CP-K® offer very high strengths and yield points.
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 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.
