摘要

PURPOSE:To obtain the Ni-austenitic stainless steel having excellent creep rupture ductility at a high temp. by limiting the component compsn. of a welding material and limiting the delta-ferrite content of a weld metal part by the mathematical expressions. CONSTITUTION:This Ni-austenitic stainless steel welding material which contains, by weight%, =0.03% C, =1.0% Si, =3.0% Mn, 0.02 to 0.07% P, 14.0 to 22.0% Cr, 10.0 to 14.0% Ni, 2.0 to 3.0% Mo, =0.04% Al, and 0.06 to 0.18%, consists of the balance substantially Fe, contains the delta-ferrite content in the weld metal part in a 1 to 6% range, and has the excellent creep rupture ductility at a high temp. The delta-ferrite content of the material is calculated by the mathematical formulas.
