Applications of S31254 Stainless Steels

Elevated oil distillation columns
Exhaust gas desulfurization scrubbers
Pumps and valves
Industrial components for oil and gas
Industrial components for food processing equipment
Pipework and manifolds
Saltwater handling systems
Flanges and manifolds
Industrial components for chemical industry
Bleaching equipment in the pulp & paper industry
Desalination equipment
Heat exchangers

Alloy 254 SMO is a very 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 uniform corrosion. Alloy 254 SMO is substantially stronger than common austenitic grades, with strength nearly twice that of 300 series stainless steel. It is also characterized by high ductility and impact strength.

With high levels of chromium, molybdenum, and nitrogen, Alloy 254 SMO is frequently used in high chloride environments, such as brackish water, seawater, pulp mill bleach plants, and other chloride process streams. In some applications it has even been found to be a more cost-effective substitute for high nickel and titanium alloys.

Additional Applications

Petroleum production
Saltwater handling
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

ASTM/ASME: UNS S31254
EURONORM: FeMi35Cr20Cu4Mo2
DIN: 2.4660

Corrosion Resistance

Excellent resistance to pitting and crevice corrosion due to its high chromium, molybdenum, and nitrogen content
Very low carbon content minimizes risk of carbide precipitation during heating
Excellent resistance in water containing chlorides, suitable for prolonged seawater exposure without crevice corrosion
