Carbon steels is successfullygo through heat-treatment which have a carbon content in the range of 0.30?1.70% by weight. because of carbon percentage content increase, steel get ability to become more harder and stronger through heat treating application as well as it becomes less ductile.In carbon steels, the higher carbon content lower the melting point and reduces weldability.
