Abstract

The invention relates to a method for producing a component from a medium-manganese flat steel product with 4 to 12 wt % Mn, preferably more than 5 to less than 10 wt % Mn, and with TRIP/TWIP effect. In order to improve the degrees of deformation of the shaped component while at the same time reducing the forming forces, the invention proposes shaping the flat steel product into a component in a first shaping step at a temperature of the flat steel product of 60° C. to below Ac3, preferably from 60° C. to 450° C. The invention also relates to a component produced according to said method and to a use for said components.
