What is Duplex 2507?

Duplex 2507 is a super duplex austenitic grade of stainless steel. The basic chemistry or chemical makeup of the 2507 Super Duplex Wnrf Flange includes elements such as 25% chromium, 4% molybdenum, and 7% nickel in its alloy. The Sa182 F11 Flange alloy is designed to be used for applications that require exceptional strength and corrosion resistance.

2507 Duplex Flange Key Benefits:

  • Very high resistance to pitting, erosion and crevice corrosion, as well as corrosion fatigue

  • Excellent resistance to stress corrosion cracking (SCC) in chloride environments

  • High resistance to general corrosion in acids

  • Very high mechanical strength

  • Good weldability: Can be readily joined to itself or other materials

  • High thermal conductivity

  • Low coefficient of thermal expansion, close to that of carbon steel.

2507 Duplex Flange Application:

  • 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 flanges for their ability to withstand a high mechanical load in seawater.

  • Super Duplex 2507 flanges 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 flanges.
