Difference Between Hot And Cold Sheet Steel

Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering.

Difference between hot and cold sheet steel.

The following are some of the key differences in hot rolled vs cold rolled steel. Hot rolled steel comes with a scaly surface slightly rounded edges and corners and the surface is non oily. 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.

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. Cold rolled steel has an oily or greasy finish very smooth surface and very sharp edges. 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.

Compared to hot rolled steel cold rolled steel has a nearly 20 increase in strength through the use of strain hardening. Hot rolled steel involves rolling the steel above re crystallization temperatures. The smaller products are also much more tolerant than the larger hot rolled versions. One important difference to understand is hot rolled steel and cold rolled steel.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. The basic difference between. This lack of knowledge concerning the two types of steel is more common than you would think. In this article we will compare hot rolled vs cold rolled steel sheets.

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. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. 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.
