Cold Rolled Steel Vs Hot Rolled Sheet

Hot rolled steel has a blue gray appearance and a rough feel once it completes the rolling process and will remain malleable and soft.

Cold rolled steel vs hot rolled sheet.

As an example a hot rolled steel product may have a yield strength of 235 mpa. Cold rolled steela rolling process at temperatures that. However this doesn t automatically mean cold is better just because it s stronger and more expensive. The rolls induce plastic deformation.

Hot rolled steel is weaker than cold rolled but it s also cheaper since it doesn t go through the second production process. 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. 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. 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 pros and cons of hot rolled steel come down to strength versus price. It is also used to produce sheet metal. Hot rolling is mainly used to produce simple cross sections or sheet metal. 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 is more malleable allowing it to be forced into a variety of different shapes. Hot rolled steel sheets are used in fabrication work where aesthetics and quality are not very important. Thus the yield strength of cold rolled steel is higher than that of hot rolled steel. In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa.

All of ours ub uc pfc rsa flats are hot rolled whereas shs chs rhs that we provide are cold rolled structural steel. This looser tolerance makes it easier to force the metal into a variety of different shapes. Hot rolled steel is malleable and perfect for industrial applications such as structural beams rail tracks and sheet metal. Hot rolled steel is easier to make to shape and form.

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. 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. When the hot rolled metal cools it will reconfigure making the finished product with a looser tolerance when compared to the cold rolled metal. The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications.
