Hastelloy B-3

Hastelloy® B-3® is a nickel-molybdenum alloy with excellent resistance to hydrochloric acid at all concentrations and temperatures. It also withstands sulfuric, acetic, formic and phosphoric acids, and other nonoxidizing media. B-3 alloy has a special chemistry designed to achieve greater thermal stability than B-2 alloy, resulting in easier fabrication.

Because this alloy contains no significant chromium addition it should NOT be used in oxidizing media or in presence of oxidizing salts, such as ferric or cupric salts. The latter may form when iron or copper is present in a system containing hydrochloric acid. Likewise alloy B-3 does not withstand wet chlorine gas or hypochlorite bleach.
