Zusammenfassung:	PURPOSE:To obtain a heat-resistant alloy for a metallic mold for molding with high hardness and toughness as well as superior resistance to wear, thermal shock and oxidation by adding specified amounts of C, Cr, Ni, Si, Mn, W, Mo, Ti and Al to Fe. CONSTITUTION:This heat resistant alloy for a metallic mold for molding consists of, by weight, 0.55-2.5% C, 0.1-3% Si, 0.1-2% Mn, 10-39% Cr, 20-65% Ni, 0.1-10% W, 0.1-10% Mo, 0.01-4.5% Ti, 0.01-4.5% Al and the balance Fe with inevitable impurities. The alloy may further contain 1-10% Co and one or more amont 0.005-0.5% N, 0.01-1.5% Nb, 0.01-1.5% Ta, 0.001-0.2% B and 0.001-0.2% Zr. The alloy has high hardness at ordinary temp. and high temp. and high toughness, so it shows stable performance for a long period, when used as the material of a metallic mold for molding.
