SMO 254 (en 1.4547 / 254 smo material) also known as 6mo Stainless Steel (6Mo) with UNS S31254 is a high Molybdenum (Molybdenum Metal) i.e 6 Molybdenum and Nitrogen alloyed Super Austenitic Stainless Steel with low Carbon content. 6Mo Material (6Moly) is designed with a combination of Nickel and Copper (ck3mcun), impact tough resistance to chloride stress corrosion cracking, and pitting and crevice corrosion with strength that is twice that of the stainless steel 300 series, especially in environments containing halite Ions, e.g. chloride, bromide and fluoride solutions. 254 SMO Stainless Steel (S31254 / Mo 6) is also characterized by high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen (ck3mcun material), 6 Moly Stainless Steel (SMO254) is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, etc.

6 Moly Material ( EN 1.4547/ UNSS31254 Alloy 6Mo / SMO254) has been reported to be a cost-effective substitute for high nickel and titanium alloys. 6 molybdenum (Molybdenum Metal) is known to possess excellent workability as well. Super Austenitic Stainless Steel (S31254 Stainless Steel / Mo 6) is compatible with the common Austenitic Stainless Steels. 1.4547 Stainless Steel (254 SMO) is readily fabricated and welded. 254SMO® is a registered with Outokumpu Oyj and 254 SMO™ is a trademark owned by Avesta Sheffield AB. Thus, 6 molybdenum stainless steel (SS 254 / F44 Material) must be procured only from trusted vendors like Oshwin Overseas. 254 SMO Stainless Steel (SMO 254)also known as Sandvik 254 SMO / Avesta 254 SMO.
