Home > Duplex Steel > Duplex Steel 2205 Sheet and Plates
Duplex Steel 2205 sheets and plates are top-notch stainless steel products that boast a unique dual-phase microstructure made up of austenite and ferrite. This special structure gives them an impressive mix of mechanical strength and resistance to corrosion, making them perfect for tough industrial tasks. They stand up remarkably well against pitting, crevice corrosion, and stress corrosion cracking caused by chlorides, all while providing outstanding toughness and thermal stability. You’ll find these sheets and plates commonly used in industries like chemical processing, petrochemicals, oil and gas, marine, and power generation.
