Steel is roll pressed at a very high temperature; usually above recrystallization temperature making it easy to work with and formed. The roll pressed steel is then cooled at room temperature resulting in non-uniform shrink and scaly surface. However, the scales can be removed by grinding, sand-blasting or pickling.
The hot rolled steel is considered suitable for structural applications as well as the applications that do not require extremely precise tolerances and shapes. Hot rolled steel is used for following applications:
