An air-meltable, castable, weldable, nonmagnetic alloy resistant to corrosion in sulfuric acid over a wide range of acid strengths. The alloy consists essentially of between about 18 and about 22% by weight nickel, between about 16.8 and 19.2% by weight chromium, between about 0.35 and about 1.95% b
An air-meltable, castable, weldable, nonmagnetic alloy resistant to corrosion in sulfuric acid over a wide range of acid strengths. The alloy consists essentially of between about 18 and about 22% by weight nickel, between about 16.8 and 19.2% by weight chromium, between about 0.35 and about 1.95% by weight molybdenum, between about 2.5 and about 3.9% by weight copper, between about 3.2 and about 4.7% by weight manganese, between about 0.35% and 0.80% by weight niobium, up to about 0.7% by weight titanium, up to about 0.4% by weight tantalum, up to about 0.01% by weight boron, up to about 0.5% by weight cobalt, up to about 0.7% by weight silicon, up to about 0.08% by weight carbon, 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 0.15% by weight nitrogen, and between about 51% and about 58% by weight iron. The nickel content exceeds the chromium content by about 0.85% to about 5.2% by weight.
