Hastelloy B has good corrosion resistance to reducing environments such as moderate concentrations of sulfuric acid and other non-oxidizing acids, and is very resistant to chloride ion stress corrosion cracking, but is highly susceptible to corrosion by oxidizing environments and cannot be used. In environments containing iron or copper salts, these materials can cause corrosion quickly.
