Cold rolling increases the strength and hardness and decreases ductility of steel by rolling it at ambient temperature or below its recrystallization temperature.
Cold rolled metal sheet.
The steel is processed further in cold reduction mills where the material is cooled at room temperature followed by annealing and or tempers rolling.

In addition to improvement of mechanical properties the cold rolling produces steel plate sheet of the desired physical dimensions.
Cold rolled steel is essentially hot rolled steel that has had further processing.
Cold rolled sheet metal can be readily welded and is suitable for painting applications when the surface has been well cleaned.

The material is cooled by the use of oil which also acts as a lubricant during the rolling process.
It is a commercial quality alloy that has an oiled surface with a smooth matte finish often used in furniture home appliances and the automotive industry.
Cold rolled steel sheet is essentially hot rolled steel that has been further processed to increase its strength and strength to weight ratio.
This process will produce steel with closer dimensional tolerances and a wider range of surface finishes.
Cold rolled steels can be used to produce parts containing simple bends to parts with extreme deep drawing requirements depending on the grade and mechanical properties selected.
Sheet 1 choose product 1008 steel is a cold rolled high strength low alloy steel with excellent weldability and formability.
In general cold rolled steel sheet can hold tighter tolerances than hot rolled when machined or otherwise fabricated and provides a better overall surface finish.
Therefore cold rolled steel is less likely to fail under pressure.
