Patent ID: 11649521

Abstract:
A hot stamping component and a manufacturing method thereof include: (a) preparing a blank including 0.27 to 0.33 wt % of carbon (C), more than 0 and 0.40 wt % or less of silicon (Si), 1.10 to 1.60 wt % of manganese (Mn), more than 0 and 0.030 wt % or less of phosphorus (P), more than 0 and 0.015 wt % or less of sulfur (S), 0.10 to 0.60 wt % of chromium (Cr), more than 0 and 0.1 wt % or less of titanium (Ti), and 0.0008 to 0.0050 wt % of boron (B); (b) heat-treating the blank; and (c) molding the heat-treated blank and cooling the molded blank. The component and method may stably provide high strength by minimizing hydrogen charging in a hot stamping manufacturing process and preventing hydrogen delayed fracture due to the hydrogen charging.
