Abstract
PURPOSE:To improve creep rupture strength, etc., by subjecting, in the final heat treatment process, a steel member having a specific composition in which respective contents of Mo and W are properly regulated to normalizing and tempering in respectively specified temp. regions and then to cold working. CONSTITUTION:A ferritic steel member having a composition which consists of, by weight, 0.04-0.2% C, <=0.3% Si, <=1.5% Mn, 0.1-1% Ni, 8-13% Cr, 0.1-2.5% Mo, 0.1-4% W, 0.1-0.4% V, 0.01-0.2% Nb, <=0.03% SolAl, 0.01-0.08% N, and the balance Fe with inevitable impurities and in which Mo+1/2W=1-2.5% is satisfied and the contents of P and S among the impurities are regulated to <=0.02%, respectively, is used as a raw material. This member is normalized at a temp. between the Ac3 point and 1,200 deg.C and temperature at a temp. between 780 deg.C and the Ac1 point in the final heat treatment process and then cold-worked at 5-20% draft. By this method, a structural member excellent in swelling resistance and suitable for use in reactor core of a fast reactor can be obtained.
