Title
(EN) Nickel alloy
Abstract
(EN)

There is provided a nickel alloy having an excellent creep strength as well as high-temperature oxidation resistance. The nickel alloy of the present invention comprises, by mass percent, Cr in a range of 11.5 to 11.9%, Co in a range of 25 to 29%, Mo in a range of 3.4 to 3.7%, W in a range of 1.9 to 2.1%, Ti in a range of 3.9 to 4.4%, Al in a range of 2.9 to 3.2%, C in a range of 0.02 to 0.03%, B in a range of 0.01 to 0.03%, Zr in a range of 0.04 to 0.06%, Ta in a range of 2.1 to 2.2%, Hf in a range of 0.3 to 0.4%, and Nb in a range of 0.5 to 0.8%, the balance being Ni and unavoidable impurities, and contains carbides and borides precipitating in crystal grains and at grain boundaries.
