PURPOSE:To improve the corrosion resistance of a weld zone by welding a stainless material by using the welding material contg. <= the specified amt. of C, Si, Mn, P, S and more than the specified amt. of Ni, Cr, N, Ta. CONSTITUTION:A stainless material is welded by using the filler metal contg. <=0.02% C, <=0.1% Si, <=5% Mn, <=0.01% P, <=0.01% S, 20-22.5% Ni, 25-28% Cr, 0.05-0.3% N and 0.005-1% Ta and the barance Fe. The corrosion resistance of a weld zone can be improved by using the welding material of this composition. |
