Hot rolling is mainly used to produce simple cross sections or sheet metal.
Cold rolled vs hot rolled steel sheet.
Basic difference between hot rolled and cold rolled steel is the way they are processed.
When the hot rolled metal cools it will reconfigure making the finished product with a looser tolerance when compared to the cold rolled metal.
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.
There are some fundamental differences between these two types of metal.
Alternatively cold rolled steel has sharp edges a very smooth surface texture and an oily or greasy feel to it.
When to use hot rolled steel the pros and cons of hot rolled steel come down to strength versus price.
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.
