Cold Rolled Vs Hot Rolled Steel Sheet

Cold rolled has sharper corners and more precise dimensions than hot rolled.

Cold rolled vs hot rolled steel sheet.

Hot rolling is mainly used to produce simple cross sections or sheet metal. Cold formed is manufactured in two steps. In this article we will compare hot rolled vs cold rolled steel sheets. Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering.

Alternatively cold rolled steel has sharp edges a very smooth surface texture and an oily or greasy feel to it. 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 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.

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 rolling and cold rolling are two methods of shaping steel. This looser tolerance makes it easier to force the metal into a variety of different shapes. When to use hot rolled steel the pros and cons of hot rolled steel come down to strength versus price.

Hot rolled steel has rounded edges a rough surface texture and no grease on its finish. 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. Hot rolled is manufactured in a single or two step process heating pre rolled steel beam blanks to such a high temperature that it allows it to be easily shaped and formed into sheet pile.

Cold rolled has a smooth and shiny finish while hot rolled has a grey and scaly finish.
