ABSTRACT:
An air-meltable castable alloy, resistant to corrosion by sulfuric acid over a wide range of acid strengths and degrees of contamination. As essential constituents, the alloy contains between about 34.10 and about 39.33% by weight nickel, between about 12.50 and about 14.29% by weight chromium, between about 5.90 and about 17.89% by weight molybdenum, between about 2.90 and about 5.67% by weight copper, between about 0.10 and about 1.25% by weight silicon, between about 0.003 and about 0.15% by weight carbon, and between about 22 and about 29% by weight iron. It may also contain up to about 3.0% by weight manganese, up to about 9.80% by weight tungsten, up to about 4.68% by weight tantalum, and up to about 3.00% by weight niobium.
