254SMO Solid Round 40mm Stainless Steel Bar Black or Bright Finish
General characteristics :
Ultra 254 SMO is a 6% molybdenum and nitrogen-alloyed austenitic stainless steel with extremely high resistance to both uniform and localized corrosion. This product was developed especially for oil and gas offshore platforms and the pulp and paper industry.
Typical applications :
requiring resistance to chlorinated seawater
Flue gas cleaning
Maritime exhaust gas cleaning (EGC)
Bleaching equipment in the pulp and paper industry
Flanges and valves
Pitting and crevice corrosion Resistance to pitting and crevice corrosion is determined mainly by the chromium, molybdenum, and nitrogen content. Ultra 254 SMO has high amounts of these elements and is suitable for demanding environments like chlorinated sea water. Stress corrosion cracking Resistance to stress corrosion cracking increases with increased content of nickel and molybdenum in particular. This means that Ultra 254 SMO has very good resistance to stress corrosion cracking.
