Hastelloy B2 is a wrought nickel-molybdenum alloy that can be used in the ‘as welded’ condition. This alloy has excellent resistance to all temperatures and concentrations of hydrochloric acid. Additionally, it has good stress corrosion cracking and pitting resistance as well. However, due to the presence of high molybdenum content, this alloy is expensive.
Hastelloy B2 bars are high-performance nickel-molybdenum alloy bars known for their exceptional resistance to corrosion, especially in reducing environments. They offer superior resistance to hydrochloric acid, sulfuric acid, and other aggressive chemicals. These bars are widely used in chemical processing, pharmaceutical, and oil and gas industries for their reliability in harsh conditions. Hastelloy B2 bars exhibit excellent mechanical properties and are available in various sizes to suit diverse industrial applications.
Hastelloy B2 bars boast excellent machinability characteristics when compared with other nickel-based alloys, enabling precise shaping and customization, which facilitates use in manufacturing processes across industries that demand components with specific dimensions requirements.
Key Applications: Reactors, heat exchangers, valves and pumps exposed to highly corrosive environments. They are indispensable in pharmaceutical manufacturing for chemical synthesis and purification processes, as well as in oil & gas for downhole equipment.
