Alloy 254 SMO is a premium super austenitic stainless steel alloyed with molybdenum and nitrogen, featuring low carbon content. This advanced material delivers exceptional resistance to pitting, crevice corrosion, stress corrosion 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 offering superior performance in demanding environments.
Key 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
Material Standards
Standard
Designation
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, making it suitable for prolonged seawater exposure without crevice corrosion
