Hot stamping steel and producing method thereof

A method for manufacturing a hot stamping steel, comprising steps of:

• producing a steel plate comprising carbon (C) in an amount of about 0.22 to about 0.25 wt %, silicon (Si) in an amount of about 0.2 to about 0.3 wt %, manganese (Mn) in an amount of about 1.2 to about 1.4 wt %, titanium (Ti) in an amount of about 0.02 to about 0.05 wt %, chromium (Cr) in an amount of about 0.11 to about 0.2 wt %, boron (B) in an amount of about 0.005 to about 0.01 wt %, zirconium (Zr) in an amount of about 0.005 to about 0.02 wt %, niobium (Nb) in an amount of about 0.01 to about 0.05 wt %, tungsten (W) in an amount of about 0.1 to about 0.5 wt %, iron (Fe) constituting the remaining balance of the steel composition, all the wt % based on the total amount of the steel composition;
• plating the steel plate with zinc (Zn);
• austenitizing the steel plate;
• hot stamping the Zn-plated steel plate at a temperature of about 750 to 850° C.;
• and
• inducing martensitic transformation in the steel plate.
