Alloy 625, often referred to as Inconel 625 (where Inconel is a trademark of Special Metals Corp) is a nickel-chromium-molybdenum-niobium alloy (NiCr22Mo9Nb), supplied in the hot worked and annealed condition. Perfectly suited to the most demanding applications, it achieves high-strength levels from the solid solution effects of Molybdenum and Niobium (Colombium) from room temperature up to 800 deg C.
