UNS S32304(23Cr-4Ni-0.1N) ,UNS S31803(22Cr-5Ni-3Mo-0.1N) ,UNS S32550(22Cr-6Ni-3Mo-2Cu-0.2N) ,UNS S32750 is an austenitic stainless steel which has high molybdenum content possesses very high resistance to pitting and crevice corrosion. The metal was developed for use in halide-containing environments such as seawater. 254 SMO also shows good resistance to uniform corrosion and is superior to conventional stainless steels especially in acids containing halides.

The high levels of molybdenum in particular but also of chromium and nitrogen endow 254 SMO with extremely good resistance to pitting and crevice corrosion. The addition of copper provides improved resistance in certain acids. Futhermore, due to its relatively high nickel content in combination with the high levels of chromium and molybdenum 254 SMO possesses good resistance to stress corrosion cracking.
