Silver Tubes is one of the pioneer producers and stockiest of Super Duplex Stainless Steel UNS S32760 Tubes, which provides excellent resistance to inorganic acids, especially those containing chlorides. The high chromium and molybdenum content of Stainless Steel UNS S32760 Seamless Tubes makes it extremely resistant to uniform corrosion by organic acids like formic and acetic acid. Stainless Steel UNS S32760 Welded Tubes also offer outstanding resistance to inorganic acids, particularly those covering chlorides. Super Duplex Stainless Steel UNS S32760 EFW Tubes are suitable for service in highly corrosive conditions and where high strength is required. Meanwhile, the properties of Stainless Steel UNS S32760 ERW Tubes are widely used in offshore oil and gas exploration and production and heat exchangers in petrochemical and chemical processing. Super Duplex UNS S32760 Tubes are also suitable for hydraulic and instrumentation applications in tropical marine environments.
Super Duplex Steel UNS S32760 Tubes is characterized by very good chloride corrosion resistance, combined with very high mechanical strength. Super Duplex S32760 Tubes is mainly suitable for aggressive atmospheres like warm chlorinated acidic and seawater, chloride comprising media. Super Duplex UNS S32760 Tubes cannot be hardened by thermal treatment but does work harden. UNS S32760 Super Duplex Tubes will often perform well in environments that cause premature failure of austenitic grades. In addition, it has better resistance to seawater than Grade 316. We also offer these tubes at the best possible rates in different sizes and shapes to our clients.
