Sheet Metal Cold Rolled Vs Hot Rolled

What it s used for cold rolled steel is much more preferred in the machining world where the quality of the steel is an important factor of the quality of the final product and the appearance of the steel is also an important factor.

Sheet metal cold rolled vs hot rolled. Due to this the properties of metal is also get altered. Hot rolled steel sheets are used in fabrication work where aesthetics and quality are not very important. The yield strength and tensile strength of cold rolled will be higher than hot rolled which makes cold rolled less likely to fracture under pressure. Cold rolled steel is stored and sold in coiled form after rolling.

Hot rolled steel properties. Whereas cold rolled steel sheets are used for precision and quality fabrication work for example consumer electronics and telecom products metal furniture automobile industry etc. All cold products provide a superior surface finish and are superior in tolerance concentricity and straightness when compared to hot rolled. During heating the metal goes through different stages.

The various types mean that steel can by widely used in infrastructure appliances vehicles wind turbines and many more applications. Cold finished bars are typically harder to work with than hot rolled due to the increased carbon content. For example railway track automotive frames structural frames low accuracy sheet metal parts etc. Hot rolled close annealed sheet hrca hot rolled close annealed sheets are rolled above its recrystallization temperature which is usually 1000 degrees celcius.

However this cannot be said about cold rolled sheet and hot rolled sheet. Dimensional accuracy and surface finish are poor in hot rolled steel. As it is easy to form metal in high temperatures without any extra delays it is possible to produce it in larger quantities than cold rolled steel.
