What is the cold rolled steel? The “Cold rolled steel ” refers to the steel rolling process done at or near room temperature. Cold rolling involves the rolling of flat rolled coils and sheet products. It undergoes more processing than the hot rolled steel because more pressure is required to form its shape. It has the added effect of strengthening the material and improving the finished product's mechanical properties through work hardening.
The cold rolling process creates a finished product that has a more precise dimension than a hot rolled product. This is because melting does not take place during the rolling process unlike the hot rolled steel.
Cold rolled steel is less malleable than hot rolled steel, making it limited to only a few simple shapes. However, with uniform cross section and small transverse dimension, other cold rolled shapes can be obtained using a series of shaping operations.
It is mostly used when a surface with a better finish is required. Common applications include flat steel products for automotive parts and construction works.
