As a carburizing steel grade it is suitable for roller and ball bearings of extra light section, aero plane and motor crankshafts requiring hard surfaces for roller paths, connecting rods with case-hardened ends, as well as highly stressed gudgeon pins, gears and certain types of collets. Case hardening will give a hard wear resisting surface and tough core strength to the steel. Case hardening temperatures range from 860-960°C, followed by rapid quenching which will determine the resulting hardness.

In a Cold Drawn Bright Bar the Hot Rolled Bars are pickled and drawn through a Tungsten Carbide Die as Cold Rolled, no heating is required, that is why it is called a Cold Drawn Bright Bar.Bright Bars have a smooth and a Bright surface with Accurate Tolerance on the Dia. Accurate Tolerance means the tolerance of the Dia is very restricted i.e 0.10 mm approximatly depending on the size of the Dia and as per the customer’s specific requirement. These are the reasons why a Bright Bar enjoys advantages over a Hot Rolled Bar. Bright Bars can be used in automatic Machines for making Steel components whereas a Hot Rolled Bar cannot be used.
