PURPOSE: To provide the austenitic stainless steel welding material having an excellent creep rupture characteristic at a high temp. and embrittleness resistance by using specific material components and specific δ-ferrite ratio. ;CONSTITUTION: This welding material contains, by weight %, ≤0.03% C, ≤1.0% Si, ≤3.0% Mn, 0.01 to 0.07% P, 14.0 to 20.0% Cr, 6 to 14% Ni, 0.5 to ≤2.0% Mo, ≤0.04% Al, and 0.06 to 0.18% N, and consists of the balance substantially Fe. In addition, the δ-ferrite content calculated by the following equation 1 of the welding material is in a 1 to 10% range by volumetric %: δ-ferrite content (%)=-70.29+3.2×Creq0.031×(Nieq)2+15.661×Creq/ Nieq-0.0208×Creq×Nieq... equation 1.
