Steels are increasingly utilized in new vehicle generations, which require both high strength and good formability. Dual-phase steels meet this objective particularly well.
Thanks to a component-appropriate design and a reduction of the material thickness, this new generation of materials makes considerable contributions to lightweight automotive engineering and construction.
Tailor welded blanks are innovative products for use in lightweight construction. The thin steel sheets required here can be used in different steel grades with different thicknesses and surface coatings.
For automotive manufacturers, the key advantage of tailor welded blanks comes in the form of simple processing in the stamping plant.
Longitudinal beams are complex-shaped components. One of their key functions is the dissipation of crash energy. By choosing the right material and the right sheet thickness in the right place, vehicle weight can be reduced.
Dual phase steel is a material that is predominantly used in longitudinal beams. Tailor Welded Blanks made from dual-phase steel are deployed where crash safety, weight savings, the highest component quality or a reduction in the number of production steps are required.
