Hastelloy is a nickel-based corrosion-resistant alloy, which is mainly divided into two categories: nickel-chromium alloy and nickel-chromium-molybdenum alloy. Hastelloy has good corrosion resistance and thermal stability, and is mostly used in aviation and chemical fields.
Characteristics of Hastelloy B-2
Hastelloy B2 is a corrosion-resistant solid solution nickel-molybdenum alloy. It is characterized by significant corrosion resistance to reducing environment, excellent resistance to medium-concentrated sulfuric acid and various non-oxidizing acids, good resistance to stress corrosion cracking (SCC) caused by chloride and good resistance to various organic acids.
Typical applications of Hastelloy B-2
Hastelloy B-2 is widely used in chemical, petrochemical, energy manufacturing and pollution control fields, especially in sulfuric acid, hydrochloric acid, phosphoric acid, acetic acid and other industries. Hastelloy B-2 can adopt gas tungsten arc welding (GTAW/TIG) or gas shielded arc welding in specific environment.
