Corrosion resistance and main use environment:
INCONEL 625 is an austenitic super heat-resistant alloy with nickel as the main component. Derived from the solid solution strengthening effect of molybdenum and niobium contained in nickel-chromium alloy, it has ultra-high strength and extraordinary fatigue resistance at low temperatures to 1093°C, and is widely used in the aviation industry. Although the alloy is designed to adapt to the strength of high-temperature environments, the high content of chromium and molybdenum in the alloy has high resistance to corrosion stains and fission corrosion against many corrosive media, from highly oxidized environments to general corrosive environments. Outstanding corrosion resistance properties. INCONEL 625 also has a strong anti-corrosion effect on chloride-contaminated media such as seawater, geothermal water, neutral salt and brine.
