PROBLEM TO BE SOLVED: To provide a mold member which is used for molding a resin, particularly, a fluororesin or a polyphenylene sulfide resin, is worn little and is superior in corrosion resistance. SOLUTION: The mold member for molding a resin has a component composition comprising >40% and≤50% Cr, >0.8% and≤4% Ti, 0.5 to 4% Cu, 0.001 to 0.04% N, 0.05 to 0.5% Mn, 0.001 to 0.05% Mg, >0.1% and≤1.0% Fe,≥0.01% and <2.0% Si,≥0.01% and <1.5% Al, further one or more elements selected from (a) one or two of 0.5 to 3% Nb and 0.5 to 3% Ta, and (b) one or two of 0.1 to 1% Mo and 0.1 to 1% W, and the balance Ni with unavoidable impurities. The amount of C contained as the unavoidable impurities is adjusted to≤0.05%. COPYRIGHT: (C)2010,JPO&INPIT
