Abstract:
A strength-ductility balance at a high temperature above 1000° C., particularly a high temperature above 1050° C. is improved by rendering a chemical composition of Cr-based alloy into Cr: more than 60 mass % but less than 65 mass %, C+N: not more than 20 mass ppm, S: not more than 20 mass ppm, O: not more than 100 mass ppm, O as an oxide: not more than 50 mass ppm, and the remainder being Fe and inevitable impurities.
