Excellent resistance to hydrochloric acid at all temperatures and concentrations.
Boasts superior machinability compared to other nickel-based alloys.
High resistance to pitting and stress corrosion cracking in reducing environments.
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 premium-grade.
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 find multiple applications across industries including chemical processing, pharmaceuticals, oil & gas production and pulp and paper production. Common applications of Hastelloy B2 bars include reactors, heat exchangers, valves and pumps exposed to highly corrosive environments, providing superior corrosion resistance, machinability and weldability while prolonging critical infrastructure's longevity and reliability.
These bars are indispensable components used in vessels and piping systems where exposure to corrosion-inducing substances such as acids or bases are frequent, and for downhole equipment operating under harsh environments.
