Hot Rolled Vs Cold Rolled Steel Sheet

Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes.

Hot rolled vs cold rolled steel sheet.

The rolls induce plastic deformation. To know various materials used to manufacture sheet metal parts. As an example a hot rolled steel product may have a yield strength of 235 mpa. Cold rolled steela rolling process at temperatures that.

Cold rolled steel is stored and sold in coiled form after rolling. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications. It is also used to produce sheet metal. 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 involves rolling the steel sheets above re crystallization temperatures. 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. 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.

However this doesn t automatically mean cold is better just because it s stronger and more expensive. All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. Although this combines two processes the method as i will point out later has an advantage of economy and scheduling in the cold formed process.

In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Sheets can also be produced in cold rolled option but they are only available on special request. 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 easier to make to shape and form.

Hot rolled steel is weaker than cold rolled but it s also cheaper since it doesn t go through the second production process. The pros and cons of hot rolled steel come down to strength versus price. First hot rolled steel coil is manufactured and later it is run through a mill which forms the coil into the steel sheet pile sections. Hot rolled steel is malleable and perfect for industrial applications such as structural beams rail tracks and sheet metal.
