254SMO stainless steel coil
254SMO is a high‑alloy super‑austenitic stainless steel with high molybdenum, nitrogen and copper content. It delivers outstanding resistance to pitting corrosion, crevice corrosion and uniform corrosion in chloride‑containing environments such as seawater, brine and acidic media, with PREN value above 40. It features low carbon content for good weldability, excellent ductility and impact toughness. Supplied in solution‑annealed and pickled finish, compliant with ASTM A240 / A240M standard.
