Cold rolled steel is essentially hot rolled steel that has had further processing. The steel is processed further in cold reduction mills, where the material is cooled (at room temperature) followed by annealing and/or tempers rolling. This process will produce steel with closer dimensional tolerances and a wider range of surface finishes. The term Cold Rolled is mistakenly used on all products.All cold products provide a superior surface finish, and are superior in tolerance, concentricity, and straightness when compared to hot rolled.
This process results in higher yield points and has four main advantages:
1.Cold drawing increases the yield and tensile strengths, often eliminating further costly thermal treatments.
2.Turning gets rid of surface imperfections.
3.Grinding narrows the original size tolerance range.
4.Polishing improves surface finish.
