ASTM B335 Hastelloy B2 UNS N10665 NICKEL ALLOY SEAMLESS TUBING
Overview
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 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 B2 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 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 B2 also has excellent resistance to pitting and stress corrosion cracking.
Applications
Superior resistance to hydrochloric acid, aluminum chloride catalysts and other strongly reducing chemicals. Excellent high-temperature strength in inert and vacuum atmospheres.
Hastelloy B2 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 (please call for technical advice).

Formability
Hastelloy B2 does work harden, but can be formed when the proper precautions are taken. Sheet (0.063" thick) in the heat treated condition at 1950°F and rapid quenched has an average olsen cup depth of 0.57" or 14.5mm.
Welding
Hastelloy B2 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.
