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.

• HIP compatible

  This alloy can be used in HIP products. HIP (Hot Isostatic Pressure) allows the production of complex, irregular shapes, offering advantages such as superior microstructure, cost reduction, and custom solutions.

  Sverdrup Steel partners with MTC Powder Solutions in Sweden to supply HIP components to the energy and heavy industry markets. Mention HIP in our contact form to learn more.

  We also supply HIP for other alloys. Feel free to ask us, and we will find a solution for your request.
