Hastelloy B2 (or known as Alloy B-2) UNS Number N010665
Hastelloy B2 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.
Nickel Alloy B2 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 B2 provides
resistance to pure sulfuric acid and a number of non-oxidizing
acids.
Limiting Factors of Hastelloy B2
Alloy B-2 has poor corrosion resistance to oxidizingenvironments,
therefore, it is not recommended for use in oxidizing media or in
the presence of ferric or cupric salts because they may cause rapid
premature corrosion failure. These salts may develop when
hydrochloric acid comes in contact with iron and copper. Therefore,
if this alloy is used in conjunction with iron or copper piping in
a system containing hydrochloric acid, the presence of these salts
could cause the alloy to fail prematurely. In addition, this nickel
steel alloy should not be used at temperatures between 1000° F and
1600° F because of a reduction in the ductility in the alloy.
What are the characteristics of Hastelloy B2?
Great resistance to stress corrosion cracking and pitting
Significant resistance to reducing conditions like hydrogen
chloride, sulfuric, acetic and phosphoric acids
Resistance to hydrochloric acid at all concentrations and
temperatures.
