Super Duplex flanges

What Are Super Duplex Flanges?

Super Duplex flanges are precision-engineered components crafted from super duplex stainless steel alloys, such as UNS S32750 and UNS S32760. These alloys feature a unique combination of austenitic and ferritic microstructures, providing twice the strength of conventional stainless steel and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.

Key Features and Advantages

Superior Corrosion Resistance

  • Resists aggressive chemicals, seawater, and chlorides.
  • Perfect for harsh environments in marine and offshore industries.

Unmatched Strength

  • Twice the yield strength of standard stainless steel.
  • Performs reliably under high-pressure and high-stress conditions.

Extended Service Life

  • High resistance to fatigue and mechanical wear.
  • Reduces maintenance and replacement costs.
