摘要
The invention relates to a method for producing a component by hot-forming a pre-product composed of steel, wherein the pre-product is heated to a temperature above 60° C. and below the Ac3 transformation temperature and then formed in this temperature range, wherein the component has a minimum tensile strength of 700 MPa and high elongation at break, wherein the pre-product has the following alloy composition in percent by weight: C: 0.0005 to 0.9; Mn: more than 3.0 to 12; the remainder iron including unavoidable steel-accompanying elements, with the optional addition of one or more of the following elements (in percent by weight): Al: up to 10; Si: up to 6; Cr: up to 6; Nb: up to 1.5; V; up to 1.5; Ti: up to 1.5; Mo: up to 3; Cu: up to 3; Sn: up to 0.5; W up to 5; Co: up to 8; Zr: up to 0.5; Ta: up to 0.5; Te: up to 0.5; B: up to 0.15; P: at most 0.1, in particular 0.04; S: at most 0.1, in particular 0.02; N: at most 0.1, in particular 0.05; Ca: up to 0.1. The invention further relates to a hot-formed component produced from a steel.
