Shape & Use: A long, cylindrical solid steel bar. Frequently used in machining, engineering, and manufacturing components like axles, shafts, and fasteners.
Manufacturing Process: Created through hot rolling billets into a continuous cylindrical shape. For applications requiring tighter tolerances and smoother finishes, it is further processed by cold drawing (pulling the unheated steel through a die).
Hot rolled round bar is rolled from steel billet and bloom, is widely used in various industries due to its diverse specifications, such as in construction and engineering field, in mechanical manufacturing field, in hardware and automobile industries and for piercing seamless pipe.
