stainless steel with the super-duplex finish The term "duplex" refers to round bars that have a two-phase microstructure that is made up of grains of ferritic and austenitic stainless steel. This gives the bar its name. Compared to common austenitic or ferritic stainless steels, the strength of super duplex stainless steels is almost twice as high. In comparison to their austenitic equivalents that have equal corrosion resistance, Super Duplex stainless steels Hex Bar have lower nickel and molybdenum concentrations in their compositions.Super Duplex Bright Bar is available in a variety of finishes from India, including Peeled & Ground (sizes - 5 to 100mm dia), Drawn & Ground (sizes - 6 to 34mm dia), Spheriodised Annealed - Pickled - Phosphated - Drawn: SAPPD (wire sizes - 5 to 30mm dia), and Super Duplex RCS Bars in sizes 40 to 350mm.
Bars made from hot rolling mills or continuous cast blooms or billets can be found in a variety of shapes such as Cold Drawn Bar, Extruded Section, Hollow Bar, Hot Rolled Bar, Cold Rolled Bar, Round Bar, Flat Bar, Forged Round Bar, Billet, Ingot, Blooms, Rebar as per DIN, EN/SAE/AISI/BS, IS and et cetera standards. Duplex beams and fasteners manufacturers rely on Super Duplex Bar Stock as a key component. An austenitic and ferrite microstructure is combined in the S32750 super duplex stainless steel bar, which is stronger than austenitic and ferritic steels. In terms of corrosion resistance, Super Duplex has a higher molybdenum and chromium concentration than regular duplex grades.
