What are Duplex Steel S32205 Plates?

Duplex Steel S32205 Plates are manufactured from duplex stainless steel containing a balanced microstructure of approximately 50% austenite and 50% ferrite. This dual-phase structure combines the corrosion resistance of austenitic stainless steel with the strength of ferritic stainless steel.

Compared to conventional stainless steels such as 304 and 316, Duplex S32205 provides significantly higher tensile strength, improved resistance to chloride-induced corrosion, and excellent weldability. Because of these advantages, UNS S32205 duplex stainless steel sheet is widely used where both mechanical strength and corrosion resistance are essential.

The material is commonly supplied according to:

  • ASTM A240 UNS S32205 Plate
  • UNS S31803 / S32205 Dual Certified Plate
  • EN 10088-2 1.4462 Plates
  • EN 10028-7 1.4462 Pressure Vessel Plate
  • W.Nr. 1.4462 Duplex Steel Plate
