Girnar Steels Industries

Cold rolling technology refers to a process whereby steel or stainless steel metals are rolled at room temperature rather than being heated to 1100 degrees Celsius. Rolling steel at room temperature by passing it through rollers enables shaping.Furthermore, this thermal treatment can be used to produce flat sheets of metal, coiled products or sections. The raw material is thereby passed through rollers below its recrystallization temperature of the relevant type of steel or stainless steel. The crystalline structure is also deformed. Additionally, the grain size is reduced resulting in increased strengthening.The steel must be passed through the rollers several times to obtain the level of thickness or the shape required, this can take longer than the hot rolling process. Highlights of Cold Rolling Technology:- Smoother finishIncreased strength of up to 20 percentHigher precision than hot rolled productsMetal hardness is increasedReduces grain size of the metalHigher quality finishSmaller production batchesEfficient manufacturing process. Cold Rolled Plates are used where a nice, smooth surface is needed, and were the thickness tolerance has to be tight. The increased yield of the material is an additional advantage especially for standard austenitic stainless steels like 304L and 316L.
