Hot Vs Cold Rolled Steel Sheet

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.

Hot vs cold rolled steel sheet.

The major d ifference between hot rolled and cold rolled steel is the way they are processed. This makes hot rolled steel a good choice for the manufacturing of structural components such as i beams or simple cross sections such as rail tracks. Hot rolled steel is malleable and perfect for industrial applications such as structural beams rail tracks and sheet metal. All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel.

The rolls induce plastic deformation. Steel comes in many grades specifications shapes and finishes the world steel association lists over 3 500 different grades of steel each with unique properties. Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes. Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering.

Hot rolled steel involves rolling the steel sheets above re crystallization temperatures. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Hot rolled steel is weaker than cold rolled but it s also cheaper since it doesn t go through the second production process. To know various materials used to manufacture sheet metal parts.

It is also used to produce sheet metal. As noted in an earlier post different types of steel undergo a wide range of processes to achieve the proper physical properties many people have heard that there s a difference between hot and cold rolled steel but don t understand what how the production of hot rolled or cold rolled steel is different from one another what industries and applications hot rolled and cold rolled serve. Hot rolled steel has a blue gray appearance and a rough feel once it completes the rolling process and will remain malleable and soft. One key distinction among prefabricated steel products is the difference between hot rolled versus cold rolled steel.

Cold rolled steel is stored and sold in coiled form after rolling. As an example a hot rolled steel product may have a yield strength of 235 mpa. However this doesn t automatically mean cold is better just because it s stronger and more expensive. The pros and cons of hot rolled steel come down to strength versus price.

Hot rolled steel is easier to make to shape and form. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. Cold rolled steela rolling process at temperatures that. It may seem obvious but some types of steel are better suited for certain.
