Introduction:

Cold rolled steel is steel produced by cold rolling. Cold rolling is to further thin the steel plate to the target thickness at room temperature. The difference between cold-rolled steel and hot-rolled steel lies not in the smelting process, but in the rolling temperature, or the end temperature of rolling. The final rolling temperature is lower than the recrystallization temperature of steel to become cold-rolled steel. Hot-rolled steel is easy to roll and has high rolling efficiency. However, under hot-rolled conditions, the steel is oxidized and the surface of the product is dark gray and dull. Cold-rolled steel requires high mill power, low rolling efficiency and intermediate annealing in order to eliminate work hardening during rolling, so the cost is also high.

Use:

It is widely used in manufacturing and processing in industry, construction, transportation and other fields.

Architectural field: Cold-rolled steel is often used in the manufacture of components in architectural cities, such as mesh, wallboard, beams and columns.

Automobile East Manufacturing: Cold-rolled steel is also one of the important materials in automobile manufacturing. It has good mechanical properties and corrosion resistance, so it is widely used in the production of dry car body, door, roof and other structural parts.

Household appliance manufacturing: cold milk steel is also widely used in household appliance manufacturing industry, such as refrigerators and washing machines. It has high strength and hardness, which can ensure the stability and durability of products.

Transportation: Cold gift steel is also one of the important materials in the transportation field. It is used to manufacture components and parts of vehicles such as aircraft, trains and automobiles, such as engines, frames and tires.

Anyway， Cold-rolled steel has many advantages such as excellent strength, toughness and stability, and is widely used in various central cities.
