摘要
An object is to provide a Ni-based alloy having high strength and excellent hydrogen embrittlement resistance even in a high-temperature and high-pressure environment and particularly capable of being used for an ammonothermal pressure vessel and the like. The present invention relates to a Ni-based alloy including, in terms of mass ratios, Fe: 30 to 40%, Cr: 14 to 16%, Ti: 1.2 to 1.7%, Al: 1.1 to 1.5%, Nb: 1.9 to 2.7%, and P: 40 to 150 ppm, with the remainder being Ni and unavoidable impurities.
