STAINLESS STEEL WELDING MATERIAL

PURPOSE:To prevent the decrease in the creep rupture ductility of a weld metal after use at a high temp. for long time by using a specifically composed stainless steel welding material for welding of a high-temp. apparatus using an austenitic stainless steel.

Summary:PURPOSE:To prevent the decrease in the creep rupture ductility of a weld metal after use at a high temp. for long time by using a specifically composed stainless steel welding material for welding of a high-temp. apparatus using an austenitic stainless steel. CONSTITUTION:A material having the compsn. consisting, by weight, of 0.02- 0.07% C, 0.05-0.90% Si, 1.5-3.0% Mn, 0.01-0.04% P, <=0.03% S, 9.0-11.0% Ni, 18.0-21.0% Cr, <=3.0% Mo, <=0.15% V, <=0.10% Ti, <=0.02% B, 0.001-0.01% O, 0.005-0.10% N and the balance Fe and impurities is used for a welding material. The weld metal of which the tensile strength at ordinary and high temp. satisfies a prescribed adequate value and the creep rupture ductility after long- term use does not decrease is thus obtd.
