Hastelloy B-2 is a solid solution strengthened nickel-molybdenum alloy with remarkable resistance to reducing environments such as hydrogen hydride gas, sulfuric acid, yanoic acid, and phosphoric acid. Molybdenum is the main alloying element that provides outstanding corrosion resistance in reducing environments. This nickel-steel alloy can be used in the welded condition because it resists the formation of grain boundary carbide precipitates in the weld heat-affected zone.
This nickel alloy provides excellent resistance to yan acid in a wide range of concentrations and temperatures. In addition, Hastelloy B2 has excellent resistance to pitting, stress corrosion cracking, and knife line and heat affected zone attacks. Alloy B2 provides resistance to pure sulfuric acid and many non-oxidizing acids.
Features of Hastelloy B-2
• Very good resistance to stress corrosion cracking and pitting
• Remarkable resistance to reducing conditions such as hydrogen chloride, sulfuric acid, acetic acid and phosphoric acid
• Resistant to hydrochloric acid at all concentrations and temperatures
Hastelloy B-2 application:
Hastelloy B-2 is widely used in chemical, petrochemical, power production and pollution control fields, especially in sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid and other industries.
