2205 duplex stainless steel plates are high-performance materials combining the benefits of austenitic and ferritic stainless steels. With a balanced microstructure of approximately 50% austenite and 50% ferrite, 2205 plates offer exceptional strength (twice that of standard 304/316 grades), superior resistance to chloride stress corrosion cracking, and excellent pitting resistance. Ideal for aggressive environments, these plates are widely used in offshore, chemical, and oil/gas industries. Their high chromium (22%), molybdenum (3%), and nitrogen content ensure durability in acidic, saline, and high-pressure conditions, making them a cost-effective alternative to super-austenitic grades.
