Abstract
PURPOSE: To provide superior high temp. strengh and softening resistance to a steel contg. a specified amount of Mn, Cr and Ni as basic components by adding a specified amount of C, Si and V to the steel followed by soln. heat treatment at 1,100W 1,200°C, hot working at ≥20% final working ratio in the same temp. zone, rapid cooling and aging.
CONSTITUTION: To a steel contg., by wt., 5W30% Mn, 5W15% Cr and 2W20% Ni and satisfying Mn+2Ni≤15.5% are added 0.3W0.6% C, 0.1W1.5% Si and 1.2W2.4% V, and this steel is subjected to soln. heat treatment at 1,100W1,200°C. It is then hot worked at ≥20% final working ratio in the same temp. zone, rapidly cooled, and aged at 600W800°C. To the above-mentioned components may be added 0.05W0.5% S.
