About Alloy B-2®

Alloy B-2® is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B-2® provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media. Premature failure may occur if alloy B-2® is used where ferric iron, cupric ion and free chlorides are present.

With a high nickel content, Hastelloy B-2® is immune to chloride-induced stress corrosion cracking.
