In this process the steel is passed between two rollers, without being heated, to reduce the thickness. The steel is then heated in an annealing furnace to improve the ductile properties. Cold rolling is more time consuming, but is used because the products have better mechanical properties, better machinability, and can more easily be manipulated into special sizes and thinner gauges.
