Hastelloy B2 Features:

Hastelloy B2  (UNS N10665/W.Nr. 2.4617) is a solid solution strengthened nickel molybdenum alloy that exhibits significant resistance to reducing environments such as hydrogen chloride gas, sulfuric acid, acetic acid and phosphoric acid. Molybdenum is a major alloying element that provides significant corrosion resistance in reducing environments. This nickel alloy can be used in the as-welded condition because it resists the formation of grain boundary carbide deposits in the weld heat-affected zone.


In addition, Hastelloy B2 has excellent resistance to pitting corrosion, stress corrosion cracking, and knife line and heat-affected zone attacks. Hastelloy B2 supports resistance to pure sulfuric acid and many non-oxidizing acids.


Hastelloy B2 is suitable for most chemical process applications in the as-welded state. Ideal for equipment that handles hydrochloric acid of various concentrations and temperatures. Resistant to hydrogen chloride gas and sulfuric acid, acetic acid and phosphoric acid. 


The main high temperature applications are those requiring a low coefficient of thermal expansion. Exposure to temperatures between 540 and 815°C (1000-1500°F) should be avoided as the ductility of the alloy decreases. In oxidizing gases such as air, Hastelloy B2 can be used at temperatures up to 540°C (1000°F). In reducing gas or vacuum, the alloy can be used at 815°C (1500°F) to higher temperatures. When hydrochloric acid comes into contact with iron or copper, iron or copper salts may be formed, therefore Hastelloy B2 should not be used with copper or iron piping in systems containing hydrochloric acid.
