What are SS Duplex 2205 Plates?
SS Duplex 2205 Plates are made from duplex stainless steel that combines both ferritic and austenitic microstructures. This dual-phase structure provides enhanced strength and improved resistance to corrosion compared to conventional stainless steel grades.
Key Features of Stainless Steel Duplex 2205 Plates
✔ Excellent resistance to pitting and crevice corrosion
✔ High resistance to stress corrosion cracking
✔ Superior strength compared to austenitic stainless steels
✔ Good weldability and fabrication properties
✔ Outstanding corrosion fatigue resistance
✔ Cost-effective solution due to high strength-to-weight ratio
The high chromium, molybdenum, and nitrogen content in Duplex 2205 Plates significantly enhances their corrosion resistance, particularly in chloride-containing environments.
