Manufacturer qualification
Alloy 254SMO / 6Mo / F44 is a fully austenitic alloy containing 6% Molybdenum and offers excellent corrosion resistance in a wide variety of aggressive aqueous environments.
It replaces conventional austenitic stainless steels ( AISI 316 and 317 ), where their capabilities are pushed to their performance limits. The alloy, therefore, falls into a “super austenitic stainless steel” category. It may also represent an economical alternative to higher nickel alloys in some marine and chemical processing environments. Alloy S31254 / 1.4547 is particularly suitable for handling high chloride environments such as brackish water, sea water, caustic chlorides and paper mill bleach systems.
Alloy F44 / 254 SMO is supplied in:
- Sheets and plates
- Rolled plates and forged plates
- bars, round billets, ingots
- perforated bars and tubes
- forged rings, forged flat and round bars
- custom forged elements
MAIN APPLICATIONS:
- equipment for marine and offshore platforms,
- chemical and food plants, salt evaporators
- plants for bleaching cellulose and paper,
- pollution control systems, air and condenser pipes, service water pipes and feed water heaters for the energy industry.
MAIN CHARACTERISTICS
- This super-austenitic material is NACE and NORSOK approved
- Excellent resistance to corrosion in sea water and in the presence of concentrated halides
- High resistance to stress corrosion
- Resistant to crevice corrosion in sea water
- Good resistance to erosion corrosion
- Excellent ductility and impact resistance at ambient and subzero temperatures
- Low magnetic permeability
