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. Alloy 254 SMO is substantially stronger than common austenitic grades, with strength nearly twice that of 300 series stainless steel. It also features high ductility and impact strength. With high levels of chromium, molybdenum, and nitrogen, Alloy 254 SMO is ideal for high chloride environments including brackish water, seawater, pulp mill bleach plants, and other 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 waters, suitable for prolonged seawater exposure without crevice corrosion
