Difference Between Hot And Cold Sheet Steel

Compared to hot rolled steel cold rolled steel has a nearly 20 increase in strength through the use of strain hardening.

Difference between hot and cold sheet steel.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. This lack of knowledge concerning the two types of steel is more common than you would think. Despite the name this process refers to steel that is pressed with the pressure of a roller at room temperature. Hot rolled steel comes with a scaly surface slightly rounded edges and corners and the surface is non oily.

The following are some of the key differences in hot rolled vs cold rolled steel. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. As you might suspect the manufacturing process behind cold rolled steel is a bit different. The differences between hot rolled steel and cold rolled steel relates to the way these metals are processed at the mill and not the product specification or grade.

Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. 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.

Hot rolled steel involves rolling the steel above re crystallization temperatures. Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. The basic difference between. 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.

In this article we will compare hot rolled vs cold rolled steel sheets. Cold rolled steel has an oily or greasy finish very smooth surface and very sharp edges. 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. One important difference to understand is hot rolled steel and cold rolled steel.
