Hot forming steels |thyssenkrupp Steel

Steels and coatings for hot forming:
MBW^® and AS Pro

For hot forming thyssenkrupp supplies hot-rolled, cold-rolled and coated MBW^® manganese-boron steels. A newcomer to the range: AS Pro, the innovative coating for significantly improved component and process reliability in automotive engineering.

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.

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.
Process: Established and patented tailored tempering 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.

Advantages of hot forming at a glance:

Highly complex part geometries can be realized
Significant weight reductions with same stiffness
Improved crash performance
High dimensional accuracy of parts
Targeted control of part properties via process parameters

The right property in the right place – tailored properties for hot-formed components

Depending on the demands placed on the components, tailored production processes like Tailored Welded Blanks, partial press hardening – be it Tailored Tempering in the die or in the hot forming furnace, flexible rolling or the use of patched blanks – comprise technical solutions for which thyssenkrupp Steel offers a wide range of uncoated and AS-coated MBW^® steels for hot forming. All these solutions show weight saving potential for crash-relevant structural car parts with additional local optimization of properties. A Tailored Welded Blank, can, for instance, also be a tailored overall solution for a hot-formed door ring.

Partner for hot forming

As a partner for hot forming, thyssenkrupp offers not only the right materials but also the facilities to identify for example the ideal process parameters for hot forming. They include an in-house test center with state-of-the-art hot forming equipment that enables us to reproduce production processes on a laboratory scale. In this way we can provide extensive support during vehicle development – from part design to production readiness – through analyses (thermography, forming, simulation, etc.) and troubleshooting. We can also carry out FEM simulations to examine processes, part feasibility and microstructures. Contact us to find out more.
