ALLOY 625 TUBING

Alloy 625 is an austenitic nickel alloy resistant to crevice corrosion and oxidation, specifically under a wide range of temperatures from cryogenic to 1800°E . This makes the product well suited for nuclear and aerospace applications. The main feature of alloy 625 is the addition of niobium which increases the strength of the tubing without heat treating.
