Cold Rolled Vs Hot Rolled Steel Sheet

Hot rolled steel involves rolling the steel above re crystallization temperatures.

Cold rolled vs hot rolled steel sheet.

During cold rolling the steel is annealed or exposed to heat and allowed to cool which improves ductility. There are some fundamental differences between these two types of 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. During the hot rolling process steel is heated to its melting point while being worked changing the composition of the steel to make it more malleable.

Hot rolled steel is rolled or shaped at a high temperature while cold rolled steel is rolled at room temperature. When to use hot rolled steel the pros and cons of hot rolled steel come down to strength versus price. Alternatively cold rolled steel has sharp edges a very smooth surface texture and an oily or greasy feel to it. Cold formed is manufactured in two steps.

Hot rolled steel has rounded edges a rough surface texture and no grease on its finish. Hot rolling is mainly used to produce simple cross sections or sheet metal. Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish. Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering.

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. Hot rolling and cold rolling are two methods of shaping steel. In this article we will compare hot rolled vs cold rolled steel sheets. Cold rolled has sharper corners and more precise dimensions than hot rolled.

This looser tolerance makes it easier to force the metal into a variety of different shapes.
