Beschreibung
Zusammenfassung:	A Ni-based alloy consisting of, in terms of mass%: 0.10% < C ≤ 0.30%; Si ≤ 0.50%; Mn < 0.50%; P < 0.030%; S < 0.010%; Cu ≤ 3.00%; 30.0% ≤ Cr ≤ 39.0%; Mo ≤ 3.00%; Fe < 3.00%; 2.00% < Al < 5.00%; O < 0.0100%; N < 0.050%; Nb < 0.50%; V < 0.50%; Ti ≤ 0.50%; Ta≤ 0.50%; W ≤ 0.50%; and at least one selected from the group consisting of 0.0010% ≤ B ≤ 0.0100%, 0.0010% ≤ Mg ≤ 0.0100%, and 0.0010% ≤ Ca ≤ 0.0100%, with the balance being Ni and unavoidable impurities, in which the alloy comprises an austenite phase having an average grain diameter of 50.0 µm or less, a M23C6-type carbide having an average circle equivalent particle diameter of 1.0 µm or more, and a massive α-Cr phase having an average circle equivalent particle diameter of 10.0 µm or less.
