    Hastelloy B3 is nickel-molybdenum alloy which has the same excellent resistance to hydrochloric acid and other strongly reducing chemicals as Hastelloy B2, but with significantly better thermal stability, fabricability and SCC resistance.

    Hastelloy B3 has been primarily used for their resistance to corrosion in nonoxidizing environments such as HCl.But it is is not recommended for use in the presence of ferric or cupric salts because these salts can cause premature failure.

    Hastelloy B3 produced by NiWire ais well suited for equipment handling hydrochloric acid in all concentrations and temperatures. Resistant to hydrogen chloride gas and sulfuric, acetic, and phosphoric acids. Principal high-temperature uses are those in which a low coefficient of thermal expansion is required.
