Abstract

PURPOSE: To provide superior strength at high temp. and superior heat resistance to a steel contg. a prescribed amount of C, Di, Mn, Mo, Al, etc. as hot rolled by subjecting the steel to hot finish rolling under specifed conditions.
CONSTITUTION: A steel consisting of ≤0.5% C, ≤0.7% Si, 0.25W1.80% Mn, ≤1.5% Mo, ≤0.08% Al and the balance Fe is heated to the Ac3 point or above and subjected to hot finish rolling at ≥40% reduction ratio in the temp. range of the Ar3 pointWthe Ar3 point+200°C. To the steel may be added ≤10% Cr or further added ≤0.5% V and/or ≤0.2% Nb. After the hot finish rolling, slow cooling is carried out at ≤35°C/min temp. gradient.
