254SMO
254SMO is an austenitic stainless steel. Due to its high molybdenum content, it has extremely high resistance to pitting and crevice corrosion. This grade of stainless steel was developed for use in environments containing halides such as seawater. 254SMO also has good Resistant to uniform corrosion. Especially in acids containing halides, this steel is superior to ordinary stainless steel.
