Applications

Hastelloy B2 Rod is extensively used in:

Chemical reactors and heat exchangers
Piping systems handling hydrochloric acid
Pharmaceutical manufacturing equipment
Pollution control systems
Pickling and acid cleaning operations

Corrosion Resistance

Hastelloy B2 exhibits:

Outstanding resistance to hydrochloric acid at all concentrations and temperatures
Excellent resistance to sulfuric, acetic, and phosphoric acids
Superior resistance to hydrogen chloride gas
Exceptional resistance to pitting, stress corrosion cracking, and crevice corrosion
Resistance to knife-line and weld heat-affected zone attack

However, it should not be used in oxidizing environments or where oxidizing contaminants are present in reducing media, as this can lead to rapid corrosion and premature failure.
