Super Duplex Stähle

S32750 • 1.4410

Datasheet

In the solution annealed condition, Super Duplex UNS S32750 – 1.4410 has a balanced austeniticferritic microstructure, is mechanically highly resistant and shows an excellent corrosion resistance in seawater. Due to its high resistance, weight and therefore material costs can be saved compared to other qualities. This material grade is particularly suitable for applications in the Oil & Gas industry, in desalination plants, in the Chemical industry as well as for geothermal applications.
