Description
F51 is a duplex stainless steel with a 50:50 austenite, ferrite microstructure. The material combines good mechanical strength and ductility with moderate to good corrosion resistance in a variety of environments. This material is generally supplied in the annealed condition giving yield strengths in excess of 65 KSI (450Mpa), this material cannot be hardened by heat treatment but stronger surface strengths can be achieved by cold working. Typical applications include pumps, valves, pipework, flanges etc together with various applications in the oil and gas, brewing, power generation and chemical engineering industries. In fact this alloy can be used successfully as an alternative to 300 series austenitic stainless steels in almost all applications where higher mechanical strength/lower weight is required.

ASTM A182 F51duplex stainless steel baring high resistance to various forms of corrosion making them ideal for Oil and Petrochemical applications. COLDUPLEX-CS is the basic grade of duplex stainless steel based on a 22% chromium and 5% nickel content. It is suitable for applications which involve high mechanical stresses and severe corrosion conditions, particularly where there is frequent contact with high levels of chlorides, carbon dioxide and hydrogen sulphide as may be encountered in the gas, petrochemical and offshore industries.

UNS S31803 F51 – Duplex stainless Steel Forging

Forging temperature for this material should be 1100 – 1250oC Reheat as often as necessary and cool in still air.

UNS S31803 F51 – Duplex stainless Steel Machining

Material in the annealed condition is readily machinable by all conventional methods.

UNS S31803 F51 – Duplex stainless Steel Welding

F51 is readily weldable using many of the standard electric arc welding processes but oxyacetylene welding is not recommended because carbon pickup in the weld metal may occur.

UNS S31803 F51 – Duplex stainless Steel Heat Treatment

Anneal – Heat to 1020 – 1120oC ensuring sufficient time is allowed for the centre to achieve furnace temperature and hold for a time commensurate with the ruling section, followed by water quenching.
