inconel alloy 625 (uns designation n06625) is a nickel-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. Inconel 625 was developed in the 1960's with the purpose of creating a material that could be used for steam-line piping. Some modifications were made to its original composition that have enabled it to be even more creep-resistant and weldable. Because of this, the uses of inconel 625 have expanded into a wide range of industries such as the chemical processing industry, and for marine and nuclear applications to make pumps and valves and other high pressure equipment.
Because of the metal's high nb levels as well as its proposed exposure to harsh environments and high temperatures, there was concern about the weldability of inconel 625. Studies were therefore conducted to test the metal's weldability, tensile strength and creep resistance, and inconel 625 was found to be an ideal choice for welding.
