2205 Duplex Stainless Steel Plate
2205 Duplex Stainless Steel Plate is the most common grade of duplex stainless steel, featuring a microstructure with a blend of austenite and ferrite. It provides a yield strength roughly double that of standard austenitic steels (like 316L) and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking in chloride-rich media. This grade is crucial for service environments where high strength and chloride resistance are mandatory, primarily in the oil and gas industry (piping, offshore platforms), chemical processing (storage and pressure vessels), desalination plants, and pulp and paper mills.
