Home > Duplex Steel > Duplex Steel Sheet and Plates
Duplex steel sheets and plates are flat, thin sections of material produced from duplex stainless steel. Duplex stainless steel is a category of stainless steel featuring a two-phase microstructure made up of nearly equal amounts of austenite and ferrite phases. This dual-phase composition delivers a blend of outstanding corrosion resistance and high strength, which makes duplex steel sheets/plates well suited for a broad variety of uses across many industries.
