4.The characteristics of Super Duplex 2507, UNS S32750

Alloy 2507 is the most popular of the nitrogen-strengthened duplex alloys. It has corrosion resistance equivalent to the 6% molybdenum alloys, such as AL6XN®. The minimum pitting resistance number for this material is 42. Depending on the source, a minimum pitting resistance number of 32 to 40 is required for service in seawater. Compared to 316L Stainless, it can range from 2 to 3 times as strong.

5.Super Duplex 2507 Uses

  • Process and service water systems, ballast water systems, and desalinization plants utilize 2507’s resistance to chloride.
  • Mechanical assemblies and infrastructure relies on Super Duplex 2507 fasteners and flanges for their ability to withstand a high mechanical load in seawater.
  • Super Duplex 2507 fasteners are also used in offshore platforms, as well as oil & gas exploration and production to protect from seawater.
  • Power industry flue-gas desulfurization systems and geothermal exploration units also rely on 2507 fasteners.
