Applications

Alloy B-2 is suitable for use in the chemical processing industry, specifically in areas where hydrochloric acid, phosphoric and sulfuric acid are used or processed. Alloy B-2 has also been used in the production of pharmaceuticals, acetic acid, alkylation of ethylene and herbicides. Typical end use applications include pumps, valves, mechanical seals, rupture discs, flanges, fittings, tanks and vessels.

Material Summary

Alloy B2 Pipes and Tubes is a solid solution strengthened, nickel-molybdenum alloy, typically used in extreme reducing conditions. UNS N10665 Pipes and Tubes has significantly lower carbon, silicon and iron compared to its' predecessor, Alloy B (UNS N10001), making the alloy less susceptible to decreased corrosion resistance in the weld zone, in the as-welded condition.
Alloy B-2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulphuric, acetic and phosphoric acids. Hastelloy B-2 provides resistance to pure sulphuric 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.
