With our broad distribution network and dependable transportation, we guarantee that our products are delivered on time, reaching every corner of the country without delays.Super Duplex S32760 Tubes combine the characteristics and properties of both austenitic and ferritic stainless steel. Made from a balanced blend of Nickel, Molybdenum, Chromium, and Nitrogen, these tubes offer enhanced corrosion resistance and workability. Notably, our Super Duplex S32760 Tubes excel in high chloride environments, providing outstanding protection against corrosion. The Nitrogen content further ensures resistance to crevice and pitting corrosion.The presence of Chromium and Molybdenum in Super Duplex S32760 Tubes ensures exceptional resistance to chloride pitting and crevice corrosion. Additionally, these tubes exhibit remarkable strength at elevated temperatures, alongside excellent mechanical properties such as tensile and yield strength. The Super Duplex S32760 Tubes also offer superior toughness and hardness. One of the key benefits of this alloy is its ability to be heat-treated, and it also boasts good weldability and fabricability. These tubes are widely used across various industries, including Food Processing, Building Construction, Chemical and Petrochemical Processing, Marine, Dairy, and Water Treatment sectors.Super Duplex UNS S32760 Tubes combine high mechanical strength with good ductility and excellent corrosion resistance in various environments. Typically supplied in an annealed condition, this material offers yield strengths exceeding KSI. While it cannot be hardened through heat treatment, increased exterior strength can be achieved through cold working. The alloy is often provided with a Pitting Resistance Equivalent (PRE) greater than 40, ensuring superior resistance to pitting corrosion. Additionally, its elevated resistance to crevice and stress corrosion, combined with its increased strength, gives it an advantage over austenitic (300 series) and 22% Cr duplex stainless steels.
Super Duplex UNS S32760 offers excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, and for optimal corrosion resistance, a surface finish that is pickled or machined is recommended. Welding procedures for UNS S32760 are similar to those used for conventional duplex stainless steel grades, with electric arc welding processes being suitable for this super duplex stainless steel. However, welding is generally not recommended due to the risk of carbon pick-up in the weld area, so it’s advisable to consult your welding consumables supplier for detailed assistance and information on welding UNS S32760 super duplex.
While UNS S32760 (1.4501 F55) cannot be toughened by conventional heat treatments as it is a work-hardening steel, Super Duplex can be solution annealed at temperatures between 1110-1140°C, followed by water quenching.
