Inconel 625

INCONEL 625

General

Alloy 625 is suitable for a wide variety of applications. The excellent resistance to pitting and crevice corrosion is utilised in sea water applications. The high strength and oxidation resistance are beneficial in aerospace applications. The strength and general corrosion resistance see the alloy also used in heat exchangers, valves, pumps, nuclear reactors and flue gas de-sulphurisation systems.
