Nickel Alloys

INCONEL 718
2.4668

718 alloy is a precipitation-hardened inconel which allows an excellent corrosion resistance to high temperatures and very good mechanical properties (high and low temperatures). This alloy can be delivered in annealed condition to improve the machinability. It has a good weldability and excellent post-welding crack resistance.
