  1. Nickel-Chrome Alloy Inconel 625 (UNS N06625) Inconel Alloy 625 is a corrosion and oxidation resistant nickel alloy that is employed for its high strength and good aqueous corrosion resistance properties. It prevents stress corrosion cracking due to chloride ions. It is resistant to pitting and crevice corrosion. Nickel 625 is a preferably used material in chemical processing, jet engines, aerospace and marine industry and nuclear power plants.
