摘要：
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.

要解决的问题：提供耐腐蚀和抗氧化的铸造合金，其耐温度在≥800℃的温度范围内得到改善。 解决方案：耐腐蚀和抗氧化的铸造合金具有以重量计包含40-50％Cr，10-35％Fe和0.32-0.5％Si，余量基本上为Ni的组成。 合金中，优选将Cr的含量控制在46〜49％，将Si的含量控制在0.35〜0.45％。 通过将Si的含量设定在规定范围内，可以抑制在800℃以上的温度下产生σ相，进一步确保铸造时的熔融金属的流动性。 版权所有（C）2006，JPO＆NCIPI
