Abstract

See full text

There is provided a Cr-based two-phase alloy including two phases of a ferrite phase and an austenite phase that are mixed with each other. A chemical composition of the Cr-based two-phase alloy consists of a main component, an auxiliary component, impurities, a first optional auxiliary component, and a second optional auxiliary component. The main component consists of 33-61 mass % Cr, 18-40 mass % Ni and 10-33 mass % Fe, and a total content of the Ni and the Fe is 37-65 mass %. The auxiliary component consists of 0.1-2 mass % Mn, 0.1-1 mass % Si, 0.005-0.05 mass % Al, and 0.02-0.3 mass % Sn. The impurities include 0.04 mass % or less of P, 0.01 mass % or less of S, 0.03 mass % or less of C, 0.04 mass % or less of N, and 0.05 mass % or less of O.
