摘要

PURPOSE:To produce a high strength ferritic heat resisting steel excellent in high temp. strength and toughness at ordinary temp. by preparing a steel having a specific composition in which respective contents of Mo, W, Co, and B are specified. CONSTITUTION:A steel having a composition consisting of, by weight, 0.05-0.15% C, =0.20% Si, 0.05-1.50% Mn, 8.00-13.00% Cr, 0.01-1.50% Ni, 0.50-1.50% Mo, 1.00-4.O0% W, 0.05-0.40% V, 0.02-0.15% Nb, 1.00-5.00% Co, 0.002-0.050% Al, 0.0010-0.0300% B, 0.01-0.11% N, and the balance Fe with inevitable impurities is prepared. By this method, the high strength ferritic heat resisting steel having superior strength at high temp. and sufficient toughness at ordinary temp. can be obtained.
