Hot-rolled bars available in many shapes: Rounds, Squares, Hexagons, Octagons, Flat and as special profiles. Free Cutting Steel Bright provides better surface finish compared to hot rolled finish supplied by the mill. Advantages achieved include improved machinability, enhancement of physical and mechanical properties and improved dimensional tolerances and straightness.
Hot rolled steel bar is produced by using the hot rolling method, wherein the steel is processed at an extremely high temperature (far beyond the re-crystallization temperature of the crude material). These steel bars are produced and maneuvered in various diameters by altering the degree of a temperature of the metal.
Cold drawn steel, like cold rolled steel, is processed at room temperature. Cold drawn steel produces a thin shape, like a rod or wire. This is accomplished by hammering down hot rolled steel to fit through a die: a machine that turns and pulls the metal into its final elongated shape. There are cold drawn/ ground/ Peeled plain bars produced from hot rolled plain bars/ wire rods. The cross section of this final shape can be round, square, rectangular, hexagonal, or octagonal, depending on the die
