Difference between hot and cold sheet steel.

In other words understanding the differences between hot and cold rolled steel will help designers and engineers achieve better results and at the best price possible. As you might suspect the manufacturing process behind cold rolled steel is a bit different. Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering. As an example a hot rolled steel product may have a yield strength of 235 mpa.

Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. The smaller products are also much more tolerant than the larger hot rolled versions. Finished products created by the cold rolled steel process include bars strips rods and sheets which are usually smaller than the same products available through hot rolled methods. Despite the name this process refers to steel that is pressed with the pressure of a roller at room temperature.

Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. Cold rolled steel has an oily or greasy finish very smooth surface and very sharp edges. The following are some of the key differences in hot rolled vs cold rolled steel. Basic difference between hot rolled and cold rolled steel is the way they are processed.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. One important difference to understand is hot rolled steel and cold rolled steel. The main advantages of cold working are. When approaching a company for a quote on material costs for producing a product you will want to know the differences between metals.

In this article we will compare hot rolled vs cold rolled steel sheets. Hot rolled steel comes with a scaly surface slightly rounded edges and corners and the surface is non oily. This lack of knowledge concerning the two types of steel is more common than you would think. Hot rolled steel involves rolling the steel above re crystallization temperatures.
