The nickel-molybdenum alloy known as Hastelloy B2 exhibits strong resistance to reducing conditions, including phosphoric, sulfuric, and acetic acids, as well as hydrogen chloride gas. Hastelloy B2 offers resistance against certain non-oxidizing acids as well as pure sulfuric acid. The alloy must not be used in oxidising environments or in situations where reducing media contains oxidising impurities. If alloy B2 is utilised in a hydrochloric acid system with iron or copper present, premature failure could result. The resistance to a variety of organic acids and stress-corrosion cracking caused by chlorides is preferred by industry users. Because it does not develop grain boundary carbide precipitates in the weld heat-affected zone, hastelloy B2 is appropriate for the majority of chemical process applications in its as-welded state. For consistent corrosion resistance, the carbides and other phases that precipitate in the heat-affected weld zones have decreased. Additionally, alloy B2 has outstanding resistance to stress corrosion cracking and pitting.
