Abstract (en)
This invention provides a steel sheet for structural components excellent in impact absorption property comprising, in mass%, C: 0.005 to 0.05%, N: 0.01 to 0.30%, Si: 0.1 to 2%, Mn: 0.1 to 15%, Ni: 0.5 to 8%, Cu: 0.1 to 5%, Cr: 11 to 20%, Al: 0.01 to 0.5%, and a balance of Fe and unavoidable impurities, wherein Md 30 value given by equation (A) is 0 to 100 °C, and total impact energy absorption in dynamic tensile testing is 500 MJ/m 3 or greater: Md 30 = 551 - 462 C + N - 9.2 Si - 8.1 Mn - 13.7 Cr - 29 Ni + Cu
