Product Overview
Alloy 254 SMO is a high-end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content. It demonstrates outstanding resistance to pitting, crevice corrosion, stress cracking, and corrosion fatigue. With strength nearly twice that of 300 series stainless steel, it offers high ductility and impact strength while maintaining excellent corrosion resistance in high chloride environments.
Corrosion Resistance
  • Excellent resistance to pitting and crevice corrosion due to high chromium, molybdenum, and nitrogen content
  • Very low carbon content minimizes risk of carbide precipitation during heating
  • Superior resistance in chloride-containing waters, suitable for prolonged seawater exposure
Industry Applications
  • Petroleum production and offshore oil & gas equipment
  • Saltwater handling and desalination equipment
  • Food and chemical processing equipment
  • Pulp mill bleach systems and tall oil distillation columns
  • Flue gas desulphurization scrubbers
  • Pumps, valves, chokes, pipework, flanges & manifolds
  • Heat exchangers and industrial components
International Standards
  • ASTM/ASME: UNS S31254
  • EURONORM: FeMi35Cr20Cu4Mo2
  • DIN: 2.4660
