摘要：
PURPOSE:To prevent the deterioration of toughness especially in the part influenced by welding heat, and to provide the steel having excellent cold toughness by allowing the steel to contain C, Si, Mn, Al, and >=1 kind among Nb, Ti, and V in specified ratio, and regulating the amt. of residual carbon to a specific value or above. CONSTITUTION:The steel contains =0.005% residual carbon regulated by the formula, =1 kind among
