UNS S32760 super duplex stainless steel stockholders and suppliers, delivering to the whole of the UK. China JT Steel are suppliers of UNS S32760 super duplex stainless steel round bar, plate and sheet. S32760 super duplex grade has enhanced pitting and crevice corrosion resistance in comparison with the ordinary austenitic or duplex types and is suitable for use in aggressive environments. This is due to the higher additions of chromium, molybdenum and nitrogen. This austenitic stainless type grade combines high strength and good ductility with outstanding corrosion resistance qualities. UNS S32760 has excellent resistance to stress corrosion cracking and gives a high resistance to erosion corrosion and corrosion fatigue.

Applications

UNS S32760 super duplex is used in a wide range of marine, oil and gas environments. UNS S32760 is commonly used in the mining, marine, pharmaceutical, petrochemical and chemical engineering industries. Typical applications include flanges, pumps, valves, chokes, connecters and manifolds. 

Corrosion Resistance

Super duplex UNS S32760 offers high resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.  For optimum corrosion resistance a surface finish of pickled or machined is recommended.

Welding

Welding procedures are similar to those applied for conventional duplex stainless steel grades. Electric arc welding processes is suitable for UNS S32760 super duplex stainless steel, though oxyacetylene welding is not recommended due to the possibility of carbon pick up in the weld area. We recommend you contact your welding consumables supplier who should provide you full assistance and information of welding UNS S32760 super duplex.
