Remark : The properties after hot stamping has a close relationship with process. Here only for reference.

Hot stamping is the process by deforming the heated steel in a mould to make parts, which take the advantage of a specific feature of metals that the ductility of metals increases and the yield strength decreases rapidly under a high temperature. The steel sheet is heated to the austenite temperature for hot stamping, and then rapidly cooled in the mould. By such a process, parts with tensile strength above 1400MPa can be manufactured.

BR1200HS steel sheet preparation before welding : The mess on the welding area should be cleared to keep it clean and dry .
