3 Cost of Hot Rolled Steel vs. Cold Rolled Steel. Generally, the cost of cold rolled steel could be twice as much as the cost of hot rolled steel, as cold rolling is a More complex metal working process than hot rolling. There is also another finishing between hot rolling process and cold rolling process, Pickled and Oiled.
Hot Rolled Coil or Cold Rolled Coil is a stage in the steelmaking process. In it, derived from the first stage is the material, molten molding, rolling until the final stage is the sanitary products that we usually see in the market.
Specifically, cold rolled steel is with hot rolled coil as raw material, pickling to remove the oxide scale after the pressure processing, the finished cold rolling steel is called hard rolls. General speaking, cold-rolled steel such as galvanized steel, color coated steel must be annealed, so the plasticity and elongation of steel will be better.

To be specific, cold rolling take hot rolled steel coil as raw material and do press fabricating after removing oxidized skin by acid wash, its finished product is hard to roll. Generally cold rolled steel, such as galvanizing and color steel, must be annealed, so the plastic and elongation rate is better, widely used in automobile, home appliance, hardware industries.
Cold rolling is a steel plate that further thins the No.1 steel plate to a target thickness at room temperature. Compared with hot-rolled steel sheet, cold-rolled steel sheet is more precise in thickness, smooth and beautiful in surface, and has a variety of superior mechanical properties, especially in processing performance.
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.
A cold rolled metal coil is manufactured by removing rust from a hot rolled coil, soaking it in acid, then washing and drying the sheet. The sheet then passes through a reducing mill under pressure. Unlike hot rolled steel coil, it is a more finished product with a smoother surface.

FORTUNE BEST CORPORATION LIMITED is best Hot Rolled Steel Coil, Hot Rolled Steel Sheet and Hot Rolled Steel Plate supplier, we has good quality products & service from China.
Cold rolling: Using hot-rolled steel coils as raw materials, oxidizing the hides and removing the scales and then performing tandem cold rolling. The finished products are rolled hard rolls. The cold work hardening due to continuous cold deformation makes the strength, hardness, and toughness of the rolled hard rolls rise.
Metinvest enterprises produce hot-rolled coils in 1.2-25 mm thickness range in accordance with the requirements of international standards and customer's specifications. Hot roll coils are available both as hot-rolled and with special in-line treatment including controlled rolling, thermomechanical rolling, and normalized rolling).
Hot rolled steel has been rolled at high temperature from a cast steel slab more than two inches (50 mm) thick into a hot rolled steel coil as thin as 1/16 inches 90.2 mm thick. Because the steel is rolled hot, and the reduction from slab to coil is great, the coil surfaces are typically rough and slightly oxidized unless they are further , hot rolled coils cold rolled coils

The cold rolled coil is made of hot rolled coil. In cold rolled process, the hot rolled coil is rolled below the recrystallization temperature, and the generally rolled steel is rolled at room temperature. Steel sheet with high silicon content has low brittleness and low plasticity, and needs to be preheated to 200 C before cold rolling.

Difference Between Hot Rolled and Cold Rolled Steel Coil. Customers often ask us about the differences between hot rolled coil and cold rolled coil. There are some fundamental differences between these two types of metal. These differences relate to the ways these metals are processed at the mill, and not the product specification or grade.
Cold Rolled Steel Cold rolled steel is essentially hot rolled steel that has gone through more processing. To get cold rolled steel, manufacturers generally take cooled-down hot rolled steel and, hot rolled coils cold rolled coils

One such development in this field has given us the hot rolled steel coils. This is in some ways similar to the production of the cold rolled steel coils, though the major difference between the two sheet metals is the temperature that is followed during manufacturing. Hot rolled steel sheets are manufactured at higher temperature than the usual.
Cold rolled coils have received an additional treatment after it has been hot rolled, pickled and oiled. The coils are moved into a series of rollers to lower its thicknesses and to have uniform surface smoothness. The process is done at room temperature. Cold rolled coils can then be further annealed to soften the steel.
