Hot Rolled And Cold Rolled Steel Sheets

Once hot rolled steel has cooled it is then re rolled at room temperature to achieve more exact dimensions and better surface qualities.

Hot rolled and cold rolled steel sheets.

The hot rolled steel shapes are formed at elevated temperatures while the cold formed steel shapes are formed at room temperature. Cold rolled steel sheets and strips are available in a couple of different conditions including. Cold rolled steel is essentially hot rolled steel that has had further processing. Cold rolled steel is essentially hot rolled steel that has been through further processing.

For example consumer electronics and telecom products metal furniture automobile industry etc. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. 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. Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio.

Hot rolling is a mill process which involves rolling the steel at a high temperature typically at a. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. For example railway track automotive frames structural frames low accuracy sheet metal parts etc. As an example a hot rolled steel product may have a yield strength of 235 mpa.

The main advantages of cold working are. All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel. Sheets can also be produced in cold rolled option but they are only available on special request. In general cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated and provides a better overall surface finish.

Full hard half hard quarter hard and skin rolled. Cold formed steel structural members are shapes commonly manufactured from steel plate sheet metal or strip material. In general cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated and provides a better overall surface finish. Hot rolled steel is easier to make to shape and form.

Hot rolled steel sheets are used in fabrication work where aesthetics and quality are not very important. The smaller products are also much more tolerant than the larger hot rolled versions. Difference between hot rolled steel and cold rolled steel hot rolled steel.
