ABSTRACT OF THE DISCLOSURE A member adapted for use under a stress in an atmosphere of a temperature below the creep temperature and made from an Ni base alloy having a high resistance to stress corrosion cracking. The Ni alloy consists essen- tially of, by weight, 15 to 25% of Cr, 1 to 8% of Mo, 0.4 to 2% of Al, 0.7 to 3% of Ti, 0.7 to 4.5% of Nb and the balance Ni, and has an austenite matrix in which precipitat- ed is at least on of Y' phase and Y" phase. The member can suitably used as parts which are subjected to pure water in nuclear reactor.
