Corrosion Resistant Alloys fall in to two categories; heat treated alloys and cold worked (or cold hardened) alloys. The heat treated alloys are strengthened by either a quench and temper process or a precipitation heat treatment. Martensitic Stainless steels such as 13Cr-L80 are quench and tempered, while nickel alloys such as 718 and 925 are precipitation heat treated. Duplex Stainless steels such as 25Cr and Solid Solution nickel base alloys like G3 and CRA 2550E are cold worked alloys. To see more information on these alloys and others please click here.
