A heat-resistant alloy comprising, as expressed in % by weight, 0.03 to 0.1% of C, 0.2 to 0.7% of Si, 0.2 to 0.7% of Mn, 42 to 60% of Ni, 25 to 35% of Cr, 8 to 20% of W, over 0% to not more than 8% of Mo, over 0% to not more than 5% of Co, and the balance substantially Fe. The alloy has improved resistance to compressive deformation and oxidation resistance for use in oxidizing atmospheres having a high temperature of over 1250°C.
Un alliage résistant aux hautes températures comprenant, exprimé en % en poids, 0,03 à 0,1 % de C, 0,2 à 0,7 % de Si, 0,2 à 0,7 % de Mn, 42 à 60 % de Ni, 25 à 35 % de Cr, 8 à 20 % de W, plus de 0 % à un maximum de 8 % de Mo, plus de 0 % à un maximum de 5 % de Co, et le reste, substantiellement du Fe. L'alliage possède une résistance améliorée à la déformation en compression et une résistance améliorée à l'oxydation pour utilisation dans des atmosphères oxydantes à une température élevée, supérieure à 1 250 degrés C. .
