Manufacturer’s 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 performance limits are being pushed. The alloy therefore falls into the “super austenitic stainless steel” category. It can also be 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, seawater, 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 Hollow
bars and tubes
Forged rings, flat and round forged bars Forged
elements to design
MAIN APPLICATIONS:

Equipment for marine and offshore platforms,
chemical and food processing plants, salt evaporators,
pulp and paper bleaching plants,
pollution control systems, air and condenser tubing, service water piping, and feedwater heaters for the energy industry.
