Abstract (en)
[origin: WO2019085855A1] A kind of steel is able to achieve a high elongation with the steel used for hot stamping by means of simple hot stamping process. The formed component has excellent yield strength, tensile strength and elongation. The steel used for hot stamping comprises by weight percent 0.1- 0.19%of C, 5.09- 9.5%of Mn, 0.11- 0.4%of V, and 0-2%Si + Al, wherein the combination of C and V meets one of the following two requirements: 1) 0.1-0.17%of C and 0.11- 0.4%of V; and 2) 0.171- 0.19%of C and 0.209-0.4%of V.
