Introduction
 

F51 duplex steel has excellent corrosion resistance, increased resistance to chloride attack and good resistance to stress corrosion cracking. F51 tensile and yield strength is higher than conventional austenitic or ferritic grades of stainless steel. It has good weldability and good formability.

Duplex steels contain both ferritic and austenitic microstructures. They have a high chromium content and a moderate nickel content. They also caontain Molybdenum. F51 material is too low in nickel to produce a fully austenitic structure, thus producing the duplex microstructure (ferrite and austenite). The main advantage of duplex F51 / 1.4462 / UNS 31803 stainless steel is the combination of properties given by both the austenitic and ferritic structure (austeno-ferritic).

F51 Stainless Steel Applications

• Process industry components in sulphuric acid, phosphoric acid, ethylene oxide, polypropylene & PVC production

• Equipment handling organic & fatty acids, chemical storage, tankers, heat exchangers

• Marine industry and shipbuilding propellers, shafts, rudders, shaft seals, pumps, bolts, fasteners, valves, instrumentation

• Oil and chemical tankers

• Oil & Gas industry pumps, valves, pipe, vessels, wellhead equipment, subsea equipment, separators, heat exchangers

• Pollution control systems, effluent scrubbing, flue gas desulphurisation (FGD)

• Waste water treatment, sour water purification

• Pulp & paper industry applications such as pulp liquor heaters, bleach tower linings, digesters, brownstock washers

• Food industry applications including brewery piping, evaporators, hot liquor tanks, presses
