Abstract:
Provided is an ultra-high-strength steel sheet having high phosphatability and hole expandability, including, by wt %, carbon (C): 0.08% to 0.2%, silicon (Si): 0.05% to 1.3%, manganese (Mn): 2.0% to 3.0%, phosphorus (P): 0.001% to 0.10%, sulfur (S): 0.010% or less, aluminum (Al): 0.01% to 0.1%, chromium (Cr): 0.3% to 1.2%, boron (B): 0.0010% to 0.0030%, titanium (Ti): 0.01% to 0.05%, nitrogen (N): 0.001% to 0.01%, and a balance of iron (Fe) and inevitable impurities, satisfying 3.4≤Ti/N≤10, 1.0≤Mn/(Si+Cr), and 0.7≤Mn*/(Si*+Cr*)≤Mn/(Si+Cr) where Ti, N, Mn, Si, and Cr refer to a weight percent (wt %), and Mn*, Si*, and Cr* refer to an average of values obtained by GDS component analysis from the surface to the 0.1 μm position in the thickness direction.

Claim (Index 7):
The method of  claim 6 , wherein the steel material further comprising, by wt %, at least one of niobium (Nb): 0.01% to 0.05%, molybdenum (Mo): 0.01% to 0.20%, vanadium (V): 0.01% to 0.20%, and tungsten (W): 0.01% to 0.20%, and the steel material satisfies Formula 4 below,\n 0.01\u2264Nb+0.2(Mo+V+W)\u22640.05\u2003\u2003[Formula 4] where each of Nb, Mo, V, and W refers to a weight percent (wt %) of the element.
