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 B2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulphuric, acetic and phosphoric acids. Hastelloy B2 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 B2 is used where ferric iron, cupric ion and free chlorides are present.

With a high nickel content, Hastelloy B2 is immune to chloride-induced stress corrosion cracking.
