An air-meltable, castable, weldable, non-magnetic alloy resistant to corrosion in chloride-containing fluids as well as in many other corrosive streams. The alloy consists essentially of between about 20.7% and about 27.2% by weight nickel, between about 19.3% and about 22.7% by weight chromium, between about 0.94% and about 2% by weight molybdenum, between about 2.6% and about 3.2% by weight copper, between about 3.2% and about 4.2% by weight manganese, between about 0.27% and about 2.02% niobium, between about 0.10% and about 0.25% by weight nitrogen, up to about 0.08% by weight carbon, up to about 0.9% by weight silicon, up to about 0.7% by weight titanium, up to about 1% by weight vanadium, 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 1% by weight cobalt, and the balance essentially iron. The sum of the nickel and cobalt contents should be between about 21.7% and about 27.2% by weight.
