Applications of S31254 Stainless Steel
  • Elevated oil distillation columns
  • Exhaust gas desulfurization scrubbers
  • Pumps and chokes
  • Industrial components for oil and gas
  • Industrial components for food processing equipment
  • Valves and pipework
  • Saltwater handling systems
  • Flanges and manifolds
  • Industrial components for chemical industry
  • Bleaching equipment in pulp & paper industry
  • Desalination equipment
  • Heat exchangers
Alloy 254 SMO is a premium 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. The high levels of chromium, molybdenum, and nitrogen make it ideal for high chloride environments including brackish water, seawater, pulp mill bleach plants, and chloride process streams.
Additional Applications
  • Petroleum production equipment
  • Saltwater handling systems
  • Food and chemical processing equipment
  • Pulp mill bleach systems
  • Flue gas desulphurization scrubbers
  • Tall oil distillation columns
  • Offshore oil & gas production equipment
  • Desalination equipment
Standards and Certifications
  • ASTM/ASME: UNS S31254
  • EURONORM: FeMi35Cr20Cu4Mo2
  • DIN: 2.4660
Corrosion Resistance Properties
  • 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 water, suitable for prolonged seawater exposure without crevice corrosion
