Inconel® Alloy 625 is a Ni-based super alloy that possesses high strength properties and resistance to elevated temperatures. It also demonstrates remarkable protection against corrosion and oxidation. Its ability to withstand high stress and a wide range of temperatures, both in and out of water, as well as being able to resist corrosion while being exposed to highly acidic environments makes it a fitting choice for nuclear and marine applications.

It has excellent mechanical properties at both extremely low and extremely high temperatures, outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion. Alloy 625 is almost complete freedom from chloride induced stress corrosion cracking. Alloy 625 has high resistance to oxidation at elevated temperatures up to 1050C, good resistance to acids, such as nitric, phosphoric, sulfuric and hydrochloric, as well as to alkalis makes possible the construction of thin structural parts of high heat transfer.
