Characters:
254 SMO (UNS S31254) is an austenitic stainless steel which due to its 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.
