Inconel 625tube is a nickel-chromium-molybdenum alloy and Inconel 2.4856 has high strength, excellent machinability, and excellent corrosion resistance and is used in temperatures ranging from cryogenic to 980°C (1800°F). The strength of 2.4856 Inconel 625 comes from the solid solution strengthening effect of molybdenum and niobium on its nickel-chromium matrix. Nickel alloy 625 has excellent fatigue strength and stress corrosion cracking properties against chloride ions.
