With an exceptional combination of high molybdenum (6%) and nitrogen content, SMO 254 Flanges exhibit outstanding resistance to crevice and pitting corrosion even in environments with high concentrations of chlorides and halides. This makes them particularly suitable for applications involving seawater, brine, and aggressive acidic solutions. The elevated mechanical strength and good weldability of this alloy further enhance its reliability in critical operations.
