EN 1.4362 / LEAN DUPLEX UNS S32304 / EDX 2304

• Applications

  The main applications for EN 1.4362 / Lean Duplex UNS S32304 / EDX 2304 are for details with special requirements for high corrosion resistance.

  S32304 is characterized by:

  • Good resistance to stress corrosion cracking.
  • Good resistance to pitting and crevice corrosion.
  • High resistance to general corrosion.
  • High mechanical strength.
  • High resistance to erosion corrosion and corrosion fatigue.

• Heat tratment and weldability

  Solution annealing at 1020 – 1100°C followed by water quenching.

  Weldability: Very good
