Abstract
A high-strength Ni-base alloy having favorable corrosion resistance, high strength, and high ductility, around room temperature is provided. A high-strength Ni-base alloy includes: in % by mass, less than 0.01% of C, not more than 0.5% of Si, not more than 0.5% of Mn, 15 to 25% of Cr. 1.0 to 5.0% of Mo or Mo+0.5W, 0.2 to 0.8% of Al, 1.0 to 2.0% of Ti, 3.00 to 3.80% of Nb, not more than 30% of Fe, and 0.0007 to 0.010% of Mg; Ni; and impurities. A value represented by Mg/S is not less than 0.7, and an A value is not less than 0.015 and less than 0.027, the A value being represented by A value=Al/(Al+1.77(Ti−1.36C)+3.44(Nb−5.1C)).
