Abstract
PURPOSE:To manufacture the title steel plate by hot rolling a steel contg. specific ratios of C, Mn, S, Cu, P, Si, N and sol Al and winding it under specific conditions. CONSTITUTION:The steel contg., by weight, 0.0005-0.015% C, 0.05-0.5% Mn, 0.001-0.030% S, 1.0-2.2% Cu, <=0.100% P, <=1.0% Si, <=0.005% N, 0.002-0.10% sol Al and the balance Fe with inevitable impurities is hot-rolled at the temp. of >=Ar, and the hot-rolled steel strip is thereafter wound at the temp. of <=500 deg.C. By this method, the title steel plate in which the generation of pearlite is evaded and consisting essentially of a ferrite single phase is obtd.
