Hastelloy alloy material is mainly resistant to wet chlorine Du, various oxidizing chlorides, zhi chloride solution, sulfuric acid and oxidizing salt. Dao has good corrosion resistance in low temperature and medium temperature yan acid. Therefore, in the past 30 years, in harsh corrosive environment, such as chemical, petrochemical, flue gas desulfurization, pulp and paper, environmental protection and other industrial fields have a quite wide range of applications.
The alloy has the following characteristics: ① It has excellent corrosion resistance to most corrosive media in oxidation and reduction atmosphere. ② It has excellent pitting corrosion resistance, crevice corrosion and stress corrosion resistance. The high content of Mo and Cr makes the alloy resistant to chloride ion corrosion, and the W element further improves the corrosion resistance. At the same time, Hastelloy C-276 alloy is one of the only corrosion resistant materials to wet LV gas, hypochlorite and chlorine dioxide solution, and has significant corrosion resistance to high concentration of salt chloride solution such as ferric chloride and copper chloride. Suitable for all concentrations of sulfuric acid solution, is one of the few materials can be applied to hot concentrated sulfuric acid solution.

Corrosion resistance and main operating environment:
INCONEL 625 is an austenitic superheat resisting alloy with nickel as the main component. Due to the strengthening effect of molybdenum and niobium solid solution contained in nickel chromium alloy, it has ultra-high strength and extraordinary anti-fatigue characteristics at low temperature to 1093℃, and is widely used in aviation industry. Although the alloy is designed to adapt to the strength of high temperature environment, the high content of chromium and molybdenum alloy has high resistance to corrosion spots and fission corrosion of many corrosive media, from high oxidation environment to general corrosion environment, showing excellent corrosion resistance. INCONEL 625 also has superior corrosion resistance against chlorine-contaminated media such as seawater, geothermal water, neutral salts and saltwater.
