Abstract
Based on the front bumper of a commercial vehicle，the hot stamping mould was developed，and the hot stamping experiment was carried out. The laser scanning，microstructure， microhardness and mechanical properties of the components were detected. The results showed that the shape of the components meets the design requirements；the structure of components after hot stamping is martensite structure；the hardness of the components is more than HV400； the yield strength of the components is more than 1 000 MPa；the tensile strength of the components is more than 1 400 MPa；the elongation exceeds 10 %.
