Applications of S31254 Stainless Steel
- Elevated oil distillation columns
- Exhaust gas desulfurization scrubbers
- Pumps, chokes, and valves
- Industrial components for oil and gas
- Food processing equipment components
- Pipework and manifolds
- Saltwater handling systems
- Chemical industry components

- Flanges and manifolds
Alloy 254 SMO is a premium super austenitic stainless steel with enhanced molybdenum and nitrogen content and low carbon composition. This alloy demonstrates exceptional resistance to pitting, crevice corrosion, stress cracking, and corrosion fatigue. With strength nearly double that of standard 300 series stainless steel, Alloy 254 SMO maintains high ductility and impact strength while providing superior performance in high chloride environments including brackish water, seawater, pulp mill bleach plants, and chloride process streams.
Primary Applications
Due to its high molybdenum and nickel content, Alloy 254 SMO is ideally suited for high chloride environments including:
- 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
Material Standards
- 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 carbide precipitation risk during heating
- Superior resistance in chloride-containing waters, suitable for prolonged seawater exposure without crevice corrosion
