Pros and Cons of Hot Rolled Steel

When steel is rolled out into a coil, it is done at  varying temperatures. Often these are very high temperatures, anything over room temperature technically qualifies as ‘hot rolled’ steel, maybe heated up to atleast 1,000 degrees Fahrenheit. This makes the steel relatively malleable compared with cold rolled steel. Hence it can be cut , formed or welded into nearly any shape needed, unlike cold rolled steel.

Hot rolling process can greatly reduce energy consumption and cost. The plastic deformation is high during hot rolling, and the deformation resistance is low, which reduces the energy consumption of steel deformation.


Hot rolling can improve the processing performance of steel.

The coarse grains formed during the formation process are broken, the cracks are healed, the casting defects are reduced, and the microstructure is converted into a deformed structure to enhance the processing properties of steel.

Hot rolled steel is low-priced compared to cold rolled steel, mostly due to stronger properties of steel.        

 There are tons of common uses for hot rolled steel. It is most commonly made into sheet metal strips. Because of its easy deformation, hot rolled steel will take much less time than cold rolled steel.

There are also a few drawbacks with hot rolled steel: Hot rolled steel is weaker than cold rolled steel. This is due to the heat applied, which weakens the metal before it cools back down.Hot rolled steel is also generally much rougher and brittle to the touch and in texture. This is because of the cooling process involved, which can cause elements to settle in rougher places rather than a smooth finish
