Hastelloy B2

HASTELLOY B2

Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids.Hastelloy B2 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 B2 is used where iron or copper is present in a system containing hydrochloric acid.

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 HASTELLOY B-2 does not withstand wet chlorine gas or hypochlorite bleach.HASTELLOY B-2 should not be exposed to temperatures in the 1000 - 1600F range because of severe loss of ductility. In a vacuum HASTELLOY B-2 may be used from 1600F to substantially higher temperatures.

Hastelloy B2 Features
  •   Resists hydrochloric acid at all concentrations and temperatures
  •   Withstands wet HCl gas, sulfuric, acetic and phosphoric acids
  •   Excellent resistance to pitting and to stress corrosion cracking
