The present disclosure provides a method of manufacturing a hot stamping component, the method includes inserting a blank into a heating furnace, heating the blank, and transferring the heated blank from the heating furnace to a mold, wherein an air cooling time of the blank in the transferring of the blank satisfies Equation 1.

Hot stamping component and method of manufacturing the same

A hot-stamped part according to an embodiment of the present invention comprises, as a base layer, a steel comprising: 0.28-0.38 wt % of carbon (C); 0.1-0.4 wt % of silicon (Si); 1.2-2.0 wt % of manganese (Mn); from greater than 0 to 0.020 wt % of phosphorus (P); from greater than 0 to 0.003 wt % of sulfur (S); 0.1-0.5 wt % of chromium (Cr); 0.0015-0.0040 wt % of boron (B); 0.025-0.05 wt % of titanium (Ti); and the remainder of iron (Fe) and inevitable impurities, wherein the microstructure of the base layer is full martensite.
