Hot forming steels:
MBW® and tribond®
For hot forming thyssenkrupp supplies hot-rolled, cold-rolled and coated MBW® manganese-boron steels and the high-strength, high ductility coated composite tribond®.
In the automotive industry MBW® manganese-boron steels are mainly used for safety-relevant structural parts, including A- and B-pillars, bumper crossbeams, side impact beams and body reinforcements. Our MBW® steels offer extremely high strengths after hot forming while retaining very good forming properties. The steel composite tribond® is a unique combination of high strength and high ductility. tribond® 1200 was specially developed to absorb as much energy as possible in the event of axial stresses, such as those caused by a front-on collision. Typical uses include longitudinal members in cars. The higher-strength tribond® 1400 is ideal for parts subjected to high bending stresses such as B-pillars.
Our materials and automotive expertise for hot forming
- Materials: Our portfolio of hot forming steels includes hot-rolled, cold-rolled and coated MBW® manganese-boron steels and the high-strength, high ductility, AS-coated composite tribond®.
- Tailored tempering: Established and patented process for hot forming that makes it possible to integrate different, precisely controlled elongation and strength properties into different areas of the same monolithic part.
