For Marine, Chemical, Oil & Gas and Pressure Vessel Applications2205 Duplex Stainless Steel Plate Supplier
Voyage Metal supplies 2205 duplex stainless steel plates, also known as UNS S32205 / S31803, for demanding industrial environments requiring high strength, good weldability and excellent resistance to chloride corrosion. Custom cutting, surface finishing and export packing are available for international B2B projects.
What Is 2205 Duplex Stainless Steel Plate?
2205 duplex stainless steel plate is a high-performance stainless steel material with a mixed austenitic and ferritic structure. It is widely used when standard 304 or 316 stainless steel cannot provide enough strength or corrosion resistance, especially in chloride-containing environments.
High Strength
2205 duplex stainless steel provides higher strength than common austenitic stainless steels, helping reduce weight in some structural and pressure-related applications.
Chloride Corrosion Resistance
2205 stainless steel plate is often selected for seawater, chemical processing and chloride-rich service conditions where corrosion resistance is important.
Good Weldability
Duplex 2205 plate can be used for welded tanks, pressure vessels, piping components and fabricated equipment when proper welding procedures are followed.
