Stainless SteelSheet/Plate
Description (English)
2205 is a typical duplex stainless steel whose microstructure consists of approximately 50% austenite + 50% ferrite, combining the advantages of both phases. It is the most widely used duplex stainless steel, offering an exceptional balance of corrosion resistance and strength.
