SM0 254 is an austenitic stainless steel of the ELC type developed for use in seawater and other aggressive chloride-bearing media. The steel is characterised by the following properties: • excellent resistance to pitting and crevice corrosion • high resistance to general corrosion • high resistance to stress corrosion cracking • higher strength than conventional austenitic stainless steels • good weldability FORMS OF SUP P LY Seamless tube and pipe – Finishes and dimensions Seamless tube and pipe are supplied in dimensions up to 230 mm outside diameter in the solution annealed and whitepickled condition or in the bright-annealed condition. Other forms of supply • Welded tube and pipe • Fittings and flanges • Bar steel • Forged products • Cast products Impact strength Its austenitic structure gives SMO 254 very good impact strength, both at room temperature and at low temperatures 254 SMO has a very low carbon content. This means that there is very little risk of carbide precipitation during heating, for example when welding. The steel passes the Strauss test (ASTM A262, practice E) even after sensitising for one hour at 600-1000°C (1110-1830°F)
