Super Duplex 2507 Pipes (UNS S32750) are high-performance stainless steel pipes engineered for use in highly corrosive, high-pressure environments. Composed of approximately 25% chromium, 7% nickel, 4% molybdenum, and nitrogen, Super Duplex 2507 offers a unique dual-phase microstructure that combines the benefits of both ferritic and austenitic stainless steels.
These pipes provide exceptional resistance to chloride-induced pitting, crevice corrosion, and stress corrosion cracking, making them ideal for applications in offshore oil & gas, desalination plants, chemical processing, and marine environments. The high strength of Super Duplex 2507 also allows for thinner wall sections, reducing weight and cost while maintaining structural integrity.
We supply seamless and welded Super Duplex 2507 pipes in accordance with standards such as ASTM A790, ASTM A928, and ASME B36.19/B36.10. Pipes are available in various schedules and sizes, with end connections including Plain End (PE), Beveled End (BE), or Threaded End (TE). Surface finishes include mill finish, pickled and passivated, or polished, based on project requirements. click here
