Hot Vs Cold Rolled Steel Sheet

Hot rolled steel is malleable and perfect for industrial applications such as structural beams rail tracks and sheet metal.

Hot vs cold rolled steel sheet. The pros and cons of hot rolled steel come down to strength versus price. However this doesn t automatically mean cold is better just because it s stronger and more expensive. 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. It may seem obvious but some types of steel are better suited for certain.

One key distinction among prefabricated steel products is the difference between hot rolled versus cold rolled steel. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. 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. Cold rolled steel is stored and sold in coiled form after rolling.

Hot rolled steel is easier to make to shape and form. The major d ifference between hot rolled and cold rolled steel is the way they are processed. As an example a hot rolled steel product may have a yield strength of 235 mpa. 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 sheets above re crystallization temperatures. It is also used to produce sheet metal. 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 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. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. The rolls induce plastic deformation. Hot rolled steel has a blue gray appearance and a rough feel once it completes the rolling process and will remain malleable and soft.

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. Cold rolled steela rolling process at temperatures that. All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel. To know various materials used to manufacture sheet metal parts.
