Physical Properties
Alloy 625: is an austenitic nickel alloy that resists crevice corrosion and oxidation and is suitable for a wide temperature range from cryogenic to 1800°F. 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 tube without the need for heat treatment.
Fabrication Properties
Alloy 625 has excellent forming and welding characteristics, but is easily work hardened.
