Abstract

PURPOSE:To produce a steel having excellent low-temp. toughness in an electron beam weld zone by subjecting a continuously cast slab of a steel having a specific compsn. specified in the ratio of Ti, N and O to reheating at a specific temp. CONSTITUTION:The steel contg., by weight %, 0.05-0.15% C, <=0.5% Si, 0.5-2.0% Mn, <=0.025% P, <=0.005% S, <=0.004% Al, 0.005-0.015% Ti, 0.005-0.025% Nb, 0.0010-0.0035% N, and 0.0015-0.0040% O, satisfying -0.005% <=[Ti]-2[O]-3.4[N]<=+0.005% and consisting of the balance Fe and unavoidable impurities is continuously cast. After the resulted slab is reheated at <=1250 deg.C, the steel is produced. >=1 Kinds among 0.005-0.060% V, 0.005-0.015% Zr, 0.05-2.0% Ni, 0.05-1.0% Cu, 0.05-1.0% Cr, 0.05-0.40% Mo, 0.0003-0.0015% B, 0.0005-0.005% Ca, and 0.005-0.05% REM are incorporated at need into the compsn. of this steel.
