F44 / S31254 / 1.4547 Super Austenitic Stainless Steel

F44 is a super austenitic stainless steel. It has a PREN of 42 to 45. Super austenitic grades have enhanced pitting and crevice corrosion resistance compared with ordinary austenitic or duplex materials. F44 nickel and chromium contents makes it resistant to a wide range of corrosive environments. This alloy is especially resistant to non-oxidizing acids such as sulphuric and phosphoric. The high molybdenum content and nitrogen provide resistance to pitting and crevice corrosion in a wide variety of aggressive, aqueous environments, while copper enhances its resistance to sulphuric acid.

One of the outstanding attributes of F44 alloy is its resistance to environments containing halides such as chlorides. F44 is especially suited to high-chloride environments such as sea water or brackish water, caustic chlorides and pulp mill bleach systems.

Applications

Applications for F44 super austenitic stainless steel include chemical and food processing, pulp and paper bleaching plants, marine and offshore platform equipment, desalination systems, air pollution control systems, and condenser tubing, service water piping, and feed-water heaters for the power industry.
