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 can also represent a cost-effective 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 pulp mill bleach systems.

Alloy F44 / 254SMO is supplied in:

Sheets and strips
Rolled plates and forged plates
Bars, round billets, ingots
Hollow bars and tubes
Forged rings, forged flat and round bars
Forgings to drawing
Main applications

Marine and offshore platform equipment,
Chemical and food plants, salt evaporators
Pulp and paper bleaching plants,
Pollution control systems, air and condenser tubes, service water piping, and feedwater heaters for the power industry.
