Difference Between Hot Rolled And Cold Rolled Steel Sheet

One key distinction among prefabricated steel products is the difference between hot rolled versus cold rolled steel.

Difference between hot rolled and cold rolled steel sheet.

Therefore a sheet of steel processed by a single pass through a roller. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. Cold rolled steel is essentially hot rolled steel that has had further processing. The hot rolled steel comes in plus minus 0 01 inches or even more than that.

In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. Another difference that can be seen between cold rolled and hot rolled steel is that cold rolled steel has fewer carbon. Hot rolled steel sheets are used in fabrication work where aesthetics and quality are not very important. It is also used to produce sheet metal.

As an example a hot rolled steel product may have a yield strength of 235 mpa. Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes. It may seem obvious but some types of steel are better suited for certain. Finished product in hot rolled steel has oxidized steel layer but the finished product of cold rolled steel is unoxidized.

Cold rolled steela rolling process at temperatures that. Cold rolled steel is stored and sold in coiled form after rolling. Hot rolled steel is used in situations where precise shapes and tolerances are not required. Whereas cold rolled steel sheets are used for precision and quality fabrication work for example consumer electronics and telecom products metal furniture automobile industry etc.

Hot rolled steel has so many shapes but cold rolled steel has few shapes. All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel. On the contrary the cold rolled steel comes in less than 0 01 inches. The rolls induce plastic deformation.

The steel is processed further in cold reduction mills where the material is cooled at room temperature followed by annealing and or tempers rolling. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications. Cold rolling cannot reduce the thickness as hot rolling does. In size as well the hot rolled and the cold rolled steel are different.

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. 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. For example railway track automotive frames structural frames low accuracy sheet metal parts etc.
