EN 1.4410 / SUPER DUPLEX UNS S32750 / F53 / 2507

• Applications

  The main applications are for details with special requirements for high corrosion resistance.

  UNS S32750 is characterized by:

  • High resistance to stress corrosion cracking in halide containing environments.
  • High resistance to pitting and crevice corrosion.
  • High resistance to general corrosion.
  • High mechanical strength.
  • High resistance to erosion corrosion and corrosion fatigue.

• Heat treatment and weldability

  Heat Treatment
  Solution annealing in the range of 1100°C followed by water quenching.

  Weldability
  Very good.
