Abstract

PURPOSE: To make a cast steel contg. a prescribed amount each of C, Si, Mn, P, S, etc. maintain the high strength at low temp. by heat-traeating the steel to form a structure consisting of bainite and ferrite-pearlite in a prescribed ratio.
CONSTITUTION: A cast steel consisting of, by wt., 0.06W0.15% C, ≤0.6% Si, 0.5W0.8% Mn, ≤0.01% P, ≤0.01% S, 2W4% Ni, ≤0.6% Al, 0.05W0.34% Mo and the balance Fe is normalized and tempered in ≥2 steps to form a structure consisting of 30W40% bainite and the balance ferrite-pearlite. The heat-treated cast steel has high strength even in the low temp. range of -50W-100°C.
