Cold Rolled Vs Hot Rolled Steel Sheet

Hot rolled steel has rounded edges a rough surface texture and no grease on its finish.

Cold rolled vs hot rolled steel sheet.

Hot rolled steel involves rolling the steel above re crystallization temperatures. 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 annealing and or tempers rolling. In this article we will compare hot rolled vs cold rolled steel sheets. This looser tolerance makes it easier to force the metal into a variety of different shapes.

Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering. Hot rolling is mainly used to produce simple cross sections or sheet metal. 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 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.

Basic difference between hot rolled and cold rolled steel is the way they are processed.
