Super Duplex Steel Buttweld Fittings

Super Duplex Steel Buttweld Fittings are high-performance stainless steel fittings designed for extreme corrosion resistance and very high mechanical strength. These fittings offer excellent resistance to pitting, crevice corrosion, and stress corrosion cracking, making them suitable for the most aggressive service environments.

Super Duplex Steel Buttweld Fittings are manufactured in seamless and welded construction and are widely used in offshore, oil & gas, chemical processing, marine, and desalination applications where superior strength and corrosion resistance are essential.

Super Duplex Steel Buttweld Fittings are available in premium super duplex grades to meet severe service conditions. The most commonly supplied grades include UNS S32750 and UNS S32760, offering outstanding resistance to localized corrosion, high yield strength, and excellent weldability.
