F55 Quick Facts

Available in the hot worked annealed condition

Excellent corrosion resistance to a range of media

Resistant to pitting and crevice corrosion in marine and chloride containing environments

High strength compared to austenitic and 22% chrome duplex stainless steels

 

Super Duplex F55 is among the most common super duplex grade in the market. F55 is a duplex stainless steel especially designed for service in aggressive chloride-containing environments and has additions of W and Cu compared to F55.

 

Alloy F55 is a super duplex stainless steel which combines high mechanical strength and good ductility. It has excellent corrosion resistance in a range of environments. It is usually supplied in  the annealed condition and cannot be age hardened however cold working can give stronger surface strengths.

 

F55 Typical Applications

Bolts and Fasteners, pumps, valves, vessels, wellhead equipment, subsea equipment, propellers and shafts. Pumps, valves, chokes, Xmas trees, pipework / flanges, bolting, connectors & manifolds. In oil and gas industry. Equipment in defence, chemical and marine industries.

 

F55 Product Description

Material to F55 (and the other specifications listed below) is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite. The steel combines high mechanical strength (typically up to 600 MPa yield strength) and good ductility with outstanding corrosion resistance to marine environments and a wide, diverse range of oil & gas production environments. The alloy is supplied with a PREN (Pitting Resistance Equivalent) at >= 40.0 which guarantees high resistance to pitting corrosion. In addition, the steel offers high resistance to crevice corrosion and stress corrosion cracking. Ambient and sub-zero (down to minus 50 °C) notch ductility is good. These attributes mean that this super duplex steel can be used successfully as an alternative to 300 series stainless steel (such as type 316), standard 22% Cr duplex steel and precipitation hardening stainless steels. Where appropriate the alloy can be considered in lieu of more costly Grade 5 titanium or nickel based alloys.

 

All material we supply has full traceability with inspection certification in accordance with BS EN 10402 3.1. We can supply material with BS EN 10402 3.2 inspection certification on request. All information included in this sheet is intended as a guide only and is correct to the best of our knowledge.
