Hot Vs Cold Rolled Steel Sheet

Sheets can also be produced in cold rolled option but they are only available on special request.

Hot vs cold rolled steel sheet.

Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering. Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes. 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. The rolls induce plastic deformation.

The pros and cons of hot rolled steel come down to strength versus price. 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. It may seem obvious but some types of steel are better suited for certain. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa.

As an example a hot rolled steel product may have a yield strength of 235 mpa. Hot rolled steel is weaker than cold rolled but it s also cheaper since it doesn t go through the second production process. One key distinction among prefabricated steel products is the difference between hot rolled versus cold rolled steel. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications.

Hot rolled steel involves rolling the steel at high temperatures where cold rolled steel is processed further in cold reduction mills where the material is cooled followed by. The major d ifference between hot rolled and cold rolled steel is the way they are processed. All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel. Hot rolled steel has a blue gray appearance and a rough feel once it completes the rolling process and will remain malleable and soft.

Cold rolled steel is stored and sold in coiled form after rolling. Hot rolled steel is malleable and perfect for industrial applications such as structural beams rail tracks and sheet metal. It is also used to produce sheet metal. Cold rolled steela rolling process at temperatures that.

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. However this doesn t automatically mean cold is better just because it s stronger and more expensive. Hot rolled steel is easier to make to shape and form. 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.
