Abstract
A high strength, corrosion resistant alloy suitable for use in oil and gas environments includes, in weight %: 0-12% Fe, 18-24% Cr, 3-6.2% Mo, 0.05-3.0% Cu, 4.0-6.5% Nb, 1.1-2.2% Ti, 0.05-0.4% 0.05-0.2% Al, 0.005-0.040% C, balance Ni plus incidental impurities and deoxidizers. A ratio of Nb/(Ti+Al) is equal to 2.5-7.5 to provide a desired volume fraction of γ' and γ″ phases. The alloy has a minimum yield strength of 145 ksi.
