Cold rolled steel coil ASTM A1008
production
The production of cold rolled steel begins with hot rolled steel that has been pickled to remove scale and other impurities. The pickled steel is then rolled at room temperature through a series of stands to achieve the desired thickness and shape. The final product is a steel coil that has been work-hardened and annealed to achieve the desired mechanical properties.
One key advantage of cold rolled steel is its improved surface finish, which is smoother and more uniform than hot rolled steel. This makes it an ideal choice for applications that require a high-quality surface, such as painted or coated products. Cold rolled steel also has better dimensional tolerances than hot rolled steel, making it easier to work with and more suitable for applications that require tight tolerances.
