Nickel and nickel-cobalt alloys are covered by the specification ASTM B622 Alloy B2 Seamless Pipe and Tube. These Hastelloy UNS N10675 Welded Tubes have been graded according to the specification according to their chemical composition. Hastelloy B2 is a nickel-molybdenum alloy with significant resistance to reducing environments such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy B2 is resistant to pure sulfuric acid and many non-oxidizing acids. This alloy should not be used in the presence of oxidative contaminants in oxidizing or reducing media. Premature failure may occur if Alloy B2 is used in the presence of iron or copper in systems containing hydrochloric acid.
