S32750-Duplex Steel Pipes

Super Duplex UNS S32760 Pipes and Tubes represent a stainless-steel solution engineered to meet the demands of corrosive environments while delivering exceptional strength. Exhibiting excellent resistance to a wide array of media, including seawater, these pipes offer superior resistance to pitting and crevice corrosion. Available in various shapes and sizes, they cater to diverse customer requirements. However, it’s important to note that round Super Duplex UNS S32750 Pipes should not be used above 300°C due to susceptibility to precipitation of brittle microconstituents. Conversely, UNS S32750 Square Pipes boast excellent general corrosion resistance, surpassing even Gr. 316. Additionally, UNS S32750 Super Duplex Seamless Tubes demonstrate remarkable resistance to stress corrosion cracking in warm chloride environments, while the temperature range for SS 430 and Super Duplex UNS S32750 welded Tubes aligns between 950°C and 1150°C. Notably, the strength of EFW Super Duplex S3750 Tubes increases below 900°C. Solution annealing in UNS S32750 Round Tubes involves pickling with a mixture of fluoric acid and nitric acid after hot working. Moreover, Super Duplex Electropolish Tubes offer robust resistance to inorganic acids, particularly those containing chlorides.
