PROBLEM TO BE SOLVED: To provide a high-temperature corrosion-resistant alloy in which the toughness and structural stability of the conventional material are secured and also high-temperature corrosion resistance and high-temperature strength are further improved. SOLUTION: In the alloy having a composition consisting of 30 to 80 mass% Cr and the balance Fe with inevitable impurities, the total content of the impurities is made to≤0.02 mass% to improve high-temperature corrosion resistance and, if necessary,≤10 mass% W is incorporated to improve high-temperature strength, and further, if necessary,≤5 mass% Ni or either or both of≤1 mass% Nb and≤1 mass% Ti are incorporated to improve toughness.
