Abstract

PURPOSE:To manufacture the title steel whose yield point and tensile strength are increased after heating and cooling even if working strain is zero, by subjecting a killed steel contg. specified amts. of C, Mn, N and one ore more out of Nb, V and Ti as main components to solution heat treatment after which the steel is hot rolled and forced to cool under limited conditions.
