The duplex round bars are made up of a material known for the ferritic and austenitic stainless steel qualities. There are different forms such as the Duplex 2205 Hex Bar, round bar, flat bar and square bars. The different shapes help serve in different application types. The square bar is used for strength and in structural applications. The Duplex Flat Bar is used for its low weight and it is useful for structural lattices. The corrosion resistance of the material with strength makes the bars to be used in petroleum, petrochemical, marine, power generation and in many other applications.
