Alloy 625 is ideally suited for the most demanding applications, from sub-zero to extremely high temperature environments. It achieves this high strength due to the solid solution effect of molybdenum and niobium (also known as columbium) from room temperature to 800°C. Alloy 625 is typically supplied in the hot worked and annealed condition.
Alloy 625 is particularly useful where resistance to oxidation and avoidance of pitting corrosion is required. In the annealed condition, this Inconel alloy is fully austenitic and suitable for machining. Due to its high alloy content, it has excellent corrosion resistance in various severely corrosive environments. Containing nearly 60% nickel, it is virtually resistant to stress corrosion cracking.
Alloy 625 is non-magnetic and capable of operating over a wide temperature range, from cryogenics to 980 degrees Celsius. This supports applications in jet engines, heat exchangers, furnace hardware and chemical plant equipment.
