Top-quality SMO 254 Pipe Fittings, UNS S31254 Buttweld Fittings designed with ASTM A403 standards.

Creative Piping is a distinguished supplier of SMO 254 pipe fittings, offering top-tier solutions for industries requiring superior corrosion resistance and durability. SMO 254 pipe fittings are components made from a high-alloy austenitic stainless steel known as SMO 254 or 6Mo (UNS S31254). This material is designed for exceptional performance in highly corrosive environments, combining high levels of chromium, molybdenum, and nitrogen to provide excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.

SMO 254 pipe fittings are essential components in industries that require robust and reliable piping solutions capable of withstanding extreme corrosive environments. Their exceptional properties make them a preferred choice for ensuring the integrity and longevity of critical systems.

01 What is SMO 254?

SMO 254 (UNS S31254) is a high-alloy austenitic stainless steel with exceptional corrosion resistance, particularly against pitting and crevice corrosion. It contains high levels of chromium, molybdenum, and nitrogen, providing superior strength and resistance to various corrosive environments.

  • Excellent resistance to pitting and crevice corrosion
  • High resistance to stress corrosion cracking
  • Superior strength compared to standard austenitic stainless steels
  • Good weldability and formability
  • High ductility and toughness

SMO 254 offers significantly better corrosion resistance, especially in chloride-rich environments, compared to 316L and 904L stainless steels. It also has higher strength and better resistance to stress corrosion cracking, making it more suitable for extreme conditions.

SMO 254 pipe fittings typically conform to standards such as ASTM A403 (for wrought austenitic stainless steel fittings), ASME B16.9 (factory-made wrought steel butt-welding fittings), and others depending on the specific type and application.
