Stainless Steel 254SMO Features:

 It can withstand a wide range of acids due to the high alloying content of chromium and molybdenum. Resistance to pitting and crevice corrosion is determined mainly by the chromium, molybdenum, and nitrogen content. 254 SMO has high amounts of these elements and is suitable for demanding environments like chlorinated sea water. 


Resistance to stress corrosion cracking increases with increased content of nickel and molybdenum in particular. This means that 254 SMO has very good resistance to stress corrosion cracking. It is also characterized by high ductility and impact strength,with strength nearly twice that of 300 series stainless steel.
