Super Duplex UNS S32750/S32760
Super Duplex UNS S32750/S32760 is an austenitic-ferritic stainless steel. Super Duplex UNS S32750/S32760 offers excellent corrosion resistance against pitting and crevice corrosion. The chemical composition and the high chromium and molybdenum content of Super Duplex UNS S32750/S32760 ensure high tensile strengths. In addition, the chemical composition exhibits high thermal conductivity and low thermal expansion. Thus, the properties of Super Duplex UNS S32750/S32760 exceed all ordinary austenitic ferritic stainless steels.
Super Duplex UNS S32750/S32760 offers many advantages. One of these advantages is that the pipe material is easier to weld thanks to the mixing structure of austenite and ferrite. In addition, Super Duplex UNS S32750/S32760 has superior mechanical properties and significantly better resistance to stress corrosion cracking in chloride-containing environments. Thanks to its high chromium and molybdenum content, - Super Duplex UNS S32750/S32760 achieves PREN values between 38-46.
