Abstract (en)

[origin: EP2835434A2] An Ni-based alloy for forging of an embodiment contains, in mass%, C: 0.01 to 0.07%, Cr: 14 to 26%, Co: 10 to 15%, Mo: 5 to 12%, Al: 0.8 to 3%, Ti: 0.8 to 3%, and B: 0.001 to 0.006%, the balance being made of Ni and an unavoidable impurity, and satisfies a relation of 10 mass% ‰¤ Mo + 0.176Cr + 0.037Co ‰¤ 15 mass%. Further, an average thickness of a carbide precipitated along a grain boundary is 250 nm or less.
