Zusammenfassung:	Provided is a hot-stamped part including a base steel sheet, the base steel sheet including an amount of about 0.19 to about 0.25 wt% of carbon (C), an amount of about 0.1 to about 0.6 wt% of silicon (Si), an amount of about 0.8 to about 1.6 wt% of manganese (Mn), an amount of about 0.03 wt% or less of phosphorus (P), an amount of about 0.015 wt% or less of sulfur (S), an amount of about 0.1 to about 0.6 wt% of chromium (Cr), an amount of about 0.001 to about 0.005 wt% of boron (B), an amount of about 0.1 wt% or less of an additive, remaining iron (Fe), and other unavoidable impurities. In an indentation strain rate with respect to an indentation depth of about 200 nm to about 600 nm is observed in a nano indentation test, a number of indentation dynamic strain aging (DSA) is about 26 to about 40.
