Whereas cold rolled steel is processed in cold reduction mills followed by annealing and tempering.
Difference between hot rolled and cold rolled sheet metal.
Nevertheless other advantages of cold rolling include a good finish a high rate of production and a fast molding speed.
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.
The dimensions of the final product are more precise and square with a sharper edge and cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated.
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.
Some of the advantages of cold rolled steel definitely have to do with regards to product precision.
Basic difference between hot rolled and cold rolled steel is the way they are processed.
There are three main visual differences between the two processes.
In general cold rolled and cold formed steel costs more than hot rolled steel because of the extra processing steps.
When to use hot rolled steel.
Furthermore cold rolled steel is considered to be more durable compared to hot rolled steel.
Hot rolled steel has rounded edges a rough surface texture and no grease on its finish.
There are some fundamental differences between these two types of metal.
Thus the yield strength of cold rolled steel is higher than that of hot rolled steel.
In this article we will compare hot rolled vs cold rolled steel sheets.
The rolls induce plastic deformation.
In comparison a cold rolled steel product with the same chemical composition has a yield strength of 365 mpa.
