Super Duplex 2507 Connectors

Super Duplex 2507 Connectors

Duplex stainless-steels are becoming more common, being used for a number of reasons including:

  • Higher strength levels
  • Greater corrosion resistance – particularly Stress Corrosion Cracking (S.C.C.) in chlorine-bearing environments
  • Much better resistance for localized corrosion, such as pitting and crevice

The “Pitting Resistances Equivalent Number” (P.R.E.N.) of “SD 2507” (1.4410/S32750) is roughly twice as good as standard Austenitic Stainless Steels such as 304 (1.4301/S30400), or 316 (1.4401/S31600).

  • Higher resistance to erosion-corrosion and corrosion-fatigue mechanism

Common designation/names/trade names include:

  • SAF 2507
  • UNS S32750
  • EN#1.4410
  • SD 2507

The nominal chemical composition of this alloy is 25% chromium, 7% nickeled and 4% molybdenum.

Lifetime Warranty

One of the most commonly asked question we hear from potential customers is:-

“Are your tube fittings Interchangeable and intermixable with Swagelok, Hoke Gyrolok, Parker A-lok etc”.

We are so confident that our components are manufactured to the same exacting standards and tolerances that we also provide a limited lifetime warranty to eradicate the misleading claims that components cannot be intermixed.

For additional information, test reports and actual “hands on demonstrations” please contact us to find out more.
