A hot stamped product, wherein: the chemical composition, in terms of mass%, is not less than 0.06% but less than 0.20% C, 0.010-1.00% Si, 0.80-2.00% Mn, not more than 0.100% P, not more than 0.010% S, 0.010-0.500% Al, not more than 0.010% N, and 0.020-0.10% Nb; the microstructure, in terms of area ratio, is 5-50% ferrite, with the remainder being martensite; not less than 30% by area of the martensite is occupied by regions having a GAIQ value of not less than 35,000 but less than 45,000; and the maximum bending angle α (deg) according to the standard VDA238-100 of the German Association of the Automotive Industry is not less than 90. The hot stamped product has high strength, excellent bendability, and excellent crack propagation resistance. |
