About Super Duplex Plate Duplex stainless steel plate has low to moderate concentrations of nickel (between 1.5% and 8%) and moderately high levels of chromium (between 18% and 28%). Due to its chemical make-up and balanced (duplex) microstructure, which contains roughly equal volume percentages of ferrite and austenite, duplex stainless steels exhibit good corrosion resistance […]
