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 recognized for its specialized performance.
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 for their reliability in harsh conditions across various heavy industries.
Hastelloy B2 bars boast excellent machinability characteristics when compared with other nickel-based alloys, enabling precise shaping and customization. This facilitates use in manufacturing processes that demand components with specific dimensions.
