Inconel® 625 is a nickel-chromium-molybdenum alloy with niobium added to provide high strength without the need to further harden. Because of this high strength, Alloy 625 can be used to cut thickness and weight from tubing and other forms, thereby improving the transfer of heat.
This alloy is extremely corrosive resistant in severe environments. This allows for use in chemical processing, aerospace and marine engineering, and in nuclear reactors.
We supply Inconel® 625 in a variety of forms, including: Rod, Plate, Sheet, and Tube.
