About Duplex Steel S31803 Plates
Duplex steel plates are flat steel material produced by duplex stainless steel, which is a combination of austenitic and ferritic stainless steel. Due to these properties, they are ideal for high-pressure and corrosive applications, thus making them ideal for structural and industrial applications.
