Hot stamping component and manufacturing method therefor

A hot-stamped part comprising:

• a base material;
• a decarburized layer formed on the base material;
• and
• a plating layer formed on the decarburized layer,
• wherein the hot-stamped part has a tensile strength (TS) of about 1,680 MPa to 2,000 MPa, a yield strength (YP) of about 1,150 MPa to 1,500 MPa, and an elongation (EL) of about 4% to 10%.

A method of manufacturing a hot-stamped part, the method comprising:

• forming a blank by cutting a plated steel sheet having a plating layer formed on at least one surface of a base material;
• and
• heating the blank in a heating furnace comprising a plurality of sections having different temperature ranges,
• wherein the heating of the blank comprises:
• a multistage heating operation of heating the blank in stages,
• a soaking operation of soaking the blank, which has been heated in the stages, in a temperature of Ac3 to about 910° C., and
• a temperature am in the soaking operation, a total heating time bm in the heating of the blank, and a thickness of a decarburized layer cm satisfy a relational expression:
