Product Description

HASTELLOY B-2 alloy (UNS N010665/ W.Nr. 2.4858) is is a nickel-molybdenum alloy with significant resistance to reducing environments, such as hydrogen chloride gas and sulfuric, acetic and phosphoric acids. Hastelloy alloy b 2 provides resistance to pure sulfuric acid and a number of non-oxidizing acids. The alloy should not be used in oxidizing media or where oxidizing contaminants are available in reducing media. Premature failure may occur if alloy B-2 is used where iron or copper is present in a system containing hydrochloric acid.

Industry users like the resistance to a wide range of organic acids and the resistance to chloride-induced stress-corrosion cracking.

Hastelloy B2 alloy resists the formation of grain boundary carbide precipitates in the weld heat-affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat-affected weld zones have reduced precipitation of carbides and other phases to ensure uniform corrosion resistance.

Alloy B-2 also has excellent resistance to pitting and stress corrosion cracking.


Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.

Hastelloy B-2 alloy is a nickel-molybdenum alloy particularly suited for equipment handling reducing chemical environments .

Applications in the chemical process industry involving sulfuric, phosphoric, hydrochloric and acetic acid. Temperature uses vary from ambient temperature to 1500°F depending on the environments
