An air-meltable, castable, workable, weldable alloy resistant to corrosion in sulfuric acid over a wide range of acid strengths. The alloy consists essentially of between about 26.00 and about 29.13% by weight nickel, between about 23.32 and about 28.28% by weight chromium, between about 0.66 and about 1.88% by weight molybdenum, between about 2.50 and about 3.82% by weight copper, between about 3.59 and about 4.72% by weight manganese, between about 0.15 and about 1.15% by weight niobium, up to about 1% by weight titanium, up to about 1.0% by weight tan...
