F55 Duplex Stainless Steel Bar (UNS S32760)
Lork Group as a professional trustworthy Duplex Stainless Steel supplier and exporter, we produce UNS S32760 Duplex round bars & rods with high cost performance.
UNS S32760 / 1.4501 / F55 Duplex Bar is 25% chromium (austenitic / ferritic) steel with .75% tungsten and copper. It is supplied with PREn (Pitting Resistance Equivalent) at >40.00 which guarantees high resistance to pit corrosion.
UNS S32760 Duplex Bar combines high mechanical strength and good ductility with corrosion resistance to marine environments and performs at ambient and sub-zero temperatures. High resistance to abrasion, erosion and cavitation erosion and also used in sour service operation.
Our Super Duplex Steel UNS S32760 Round Bars have high strength, superior corrosion resistance, resistance to chloride-induced stress cracking, and outstanding resistance against sulphide-stress corrosion cracking in sour-gas environments.
Super Duplex Steel UNS S32760 Round Bars are used for various including Oil and Gas Applications, Hydropower, Pressure Vessels, Structural Components, Chemical Tankers, Seawater Applications, Pressure Vessels, Heat Exchangers, Marine Applications, Flue Gas Scrubbing Equipment, Pulp & Paper Industry, Offshore Oil Refining, Subsea Pipework Systems, Heat Exchangers and more.
As a leading UNS S32760 / 1.4501 / F55 supplier in China, our products pass strict quality control and testing and ensure that the products meet standards and customer requirements. Lork Group manufactures and produces duplex bars of various sizes.
