Hastelloy B

Hastelloy B is a solid solution strengthened, nickel-molybdenum alloy, with
significant resistance to reducing environments like hydrogen chloride gas, and
sulfuric, acetic and phosphoric acids. Molybdenum is the primary alloying
element which provides significant corrosion resistance to reducing
environments. This nickel steel alloy can be used in the as-welded condition
because it resists the formation of grain-boundary carbide precipitates in the
weld heat-affected zone.

This nickel alloy provides excellent resistance to hydrochloric acid at all
concentrations and temperatures. In additions, Hastelloy B2 has excellent
resistance to pitting, stress corrosion cracking and to knife-line and heat-
affected zone attack. Alloy B provides resistance to pure sulfuric acid and a
number of non-oxidizing acids.
