An air-meltable, workable, castable, weldable, machinable, nonmagnetic alloy resistant to seawater and corrosive process fluids of the type that may be circulated in seawater-cooled heat exchangers. The alloy consists essentially of between about 3% and about 8% by weight manganese, between about 12% and about 28% by weight nickel, between about 17.3% and about 19% by weight chromium, between about 0.68% and about 3.51% by weight copper, between about 0.07% and about 0.25% by weight nitrogen, between about 5.9% and about 8% by weight molybdenum, up to about 0.08% by weight carbon, up to about 1.5% by weight silicon, up to about 0.66% by weight niobium, up to about 1.32% by weight tantalum, up to about 1% by weight vanadium, up to about 1% by weight titanium, up to about 0.6% by weight of a rare earth component selected from the group consisting of cerium, lanthanum, and misch metal, up to about 5% by weight cobalt, and between about 30% and about 56% by weight iron. The titanium equals at least five times any carbon contant in excess of 0.03% by weight. The sum of the cobalt and nickel contents should not be at least about 17% but not exceed about 28% by weight. The sum of the niobium content and one-half the tantalum content should not exceed about 0.66% by weight.
