Abstract
An Al—Si coated press hardening component, wherein the Al—Si coating comprises a low-Al content ferrite layer with an Al content of less than 5 wt % and a thickness of greater than 5 μm, and having a maximum bending angle of the Al—Si coated press hardening component is greater than 65°. The thickness of the tough low-Al content ferrite layer in the Al—Si coating after hot stamping, reaching 5-100 μm, by improving the hot stamping process, so that the formation or propagation of cracks on the surface or the coating is effectively prevented, and the bendability of the pre-coated steel after hot stamping is improved. At the same time, the hot stamping process of the present invention can take into account or optimize the microstructure of the steel substrate to further improve the bendability and tensile property of the whole material.
