Difference Between Hot Rolled And Cold Rolled Steel Sheet

Thus the yield strength of cold rolled steel is higher than that of hot rolled steel.

Difference between hot rolled and cold rolled steel sheet.

It is also used to produce sheet metal. Hot rolled steel sheets are used in fabrication work where aesthetics and quality are not very important. 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. On the contrary the cold rolled steel comes in less than 0 01 inches.

One key distinction among prefabricated steel products is the difference between hot rolled versus cold rolled steel. Hot rolled steel is used in situations where precise shapes and tolerances are not required. The hot rolled steel comes in plus minus 0 01 inches or even more than that. 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.

Sheets can also be produced in cold rolled option but they are only available on special request. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa. It may seem obvious but some types of steel are better suited for certain. Hot rolled steel is more malleable allowing it to be forced into a variety of different shapes.

Cold rolled steela rolling process at temperatures that. Another difference that can be seen between cold rolled and hot rolled steel is that cold rolled steel has fewer carbon. 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.

For example railway track automotive frames structural frames low accuracy sheet metal parts etc. Hot rolled steel is easier to make to shape and form. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications. Therefore a sheet of steel processed by a single pass through a roller.

Cold rolled steel is stored and sold in coiled form after rolling. Finished product in hot rolled steel has oxidized steel layer but the finished product of cold rolled steel is unoxidized. The steel is processed further in cold reduction mills where the material is cooled at room temperature followed by annealing and or tempers rolling. 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.

Cold rolled steel is essentially hot rolled steel that has had further processing. 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. In size as well the hot rolled and the cold rolled steel are different.
