What are Super Duplex Steel UNS S32760 Flanges?

UNS S32760 is a highly sought-after super duplex stainless steel due to its distinct characteristics. Its microstructure is a balanced mix of austenite and ferrite, a dual-phased composition that is key to its unique properties.


  • Extraordinary Strength: The balanced duplex structure of S32760 Flanges provides a tensile and yield strength that is approximately twice that of standard austenitic stainless steels. This allows the flanges to withstand heavy loads and high pressures, contributing to their exceptional durability.

  • Superior Corrosion Resistance: The high content of chromium, nickel, molybdenum, and nitrogen in this alloy provides outstanding resistance to various corrosive environments. It is particularly effective against pitting, crevice corrosion, and stress corrosion cracking (SCC) in chloride-rich settings and at elevated temperatures up to 302°F (150°C).

  • Good Weldability and Durability: Despite its high alloy content, this grade can be welded using common methods without compromising its mechanical properties. Additionally, it offers excellent resistance to erosion and abrasion, making it a preferred choice for applications with abrasive media.
