PURPOSE:To improve the resistance to impact, pitting and pock mark of the deposited metal of a titled wire obtd. by using the specific compsn. contg. C, Si, Mn, P, S and O and consisting of the balance substantially Fe. CONSTITUTION:This wire for submerged arc welding has the following cmpsn. by weight %. The wire contains 0.03-1.15% C, <=0.05% Si, 1.2-2.2% Mn, <=0.030% P, and <=0.030% S and further consists of <=75ppm O and the balance Fe and inevitable components. |
