Hastelloy B2 is a nickel-molybdenum alloy resistant to reducing environments, such as hydrochloric acid and sulfuric acid. It has an improved mechanical strength compared to other nickel-base alloys, making it suitable for various applications. It includes, among others, 50% nickel, 20% molybdenum and 15-17% chromium. Adding copper gives it exceptional resistance to non-oxidizing acids, including phosphoric and sulfurous acids, and good stress corrosion cracking resistance in chloride solution.
Hastelloy B2 sheet has excellent resistance to reducing and oxidizing environments. It is used in chemical process equipment, pickling operations, oil refinery components, piping fixtures and gas scrubbing systems. It also exhibits good thermal stability and low thermal expansion rates, allowing it to be used in high-temperature applications. Additionally, it has superior strength, making it resistant to corrosion even at elevated temperatures and pressures.
