Summary:PURPOSE:To improve the resistance of the weld heat-affected zone of a high- tension low-alloy steel to cracking by plating by restricting the amounts of C, Mn, Si, Ti, Ca, Al, etc., and satisfying certain relation among the amounts. CONSTITUTION:This high-tension low-alloy steel consists of, by weight, 0.03-0.15% C, 0.6-2% Mn, 0.05-0.3% Si, 0.005-0.03% Ti, 0.001-0.005% Ca, 0.005-0.1% Al, one ore more among <=0.014% N, etc., and the balance Fe and has <=0.28 T value calculated by a formula T=C+Si/30+Mn/10-S/2+Cr/10+Mo/20+V/3+Nb/3-2Ti+3B.
