Manganese-boron steels and AS Pro coating for hot forming: Highest strength with good forming properties

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. Our MBW^® steels offer extremely high strengths after hot forming while retaining very good forming properties.

Advantages of MBW^® manganese-boron steels for hot forming at a glance:

Broad spectrum of uncoated and coated MnB steels for hot forming with strengths from 500 to 2,000 MPa after hot forming.
AS Pro, innovative coating for significantly improved component and process reliability in automotive engineering.
Very high degrees of forming possible with high final strength.
Very high potential for weight reduction in safety-relevant structural parts.

Product novelty: With AS Pro, thyssenkrupp Steel is the first steel manufacturer to launch a new, game-changing coating for hot forming ultra-high-strength MBW^® steels worldwide – to ensure maximum automobile component reliability. The new coating ensures significantly lower process-related hydrogen absorption during the annealing process in hot forming, and also makes the manufacturing process more economical.

Hot-rolled lightweight steels with optimum processability for the chassis

Warmgewalzte Leichtbaustähle mit bester Verarbeitbarkeit für das Fahrwerk

Whether microalloyed steels for suspension and axle applications, high-strength multi-phase steels for single-skin control arms, or application-optimized manganese-boron steels for precision steel tubular applications such as stabilizers, thyssenkrupp Steel offers an extensive hot-rolled portfolio for the cost-effective lightweighting of high-strength chassis components.

Our hot-rolled chassis materials are available as uncoated and coated hot wide strip and slit strip and as uncoated precision strip, on request also as slit coil.

Portfolio expansion: We have expanded the portfolio of hot-rolled microalloyed steels to include high-ductility (HD) grades. Compared with the VDA 239-100 and DIN EN 10149-2 standards, the microalloyed HD steels are characterized by a significantly narrower range of mechanical properties and increased elongation at break.

Vehicle interior: Lightweight steels for seat structures
