Zusammenfassung:PROBLEM TO BE SOLVED: To provide a corrosion resistant and oxidation resistant cast alloy whose durability in the temperature range of ≥800°C is improved. SOLUTION: The corrosion resistant and oxidation resistant cast alloy has a composition comprising, by weight, 40 to 50% Cr, 10 to 35% Fe and 0.32 to 0.5% Si, and the balance substantially Ni. In the alloy, desirably, the content of Cr is controlled to 46 to 49%, and the content of Si is controlled to 0.35 to 0.45%. By setting the content of Si to the prescribed range, the generation of a σ phase in the temperature of ≥800°C is suppressed, and further, the fluidity of molten metal at the time of casting is secured.
