Advantages
Accurate in size, uniform in thickness, and the thickness difference of the coils generally does not exceed 0.01-0.03 mm or less, which can meet the requirements of high-precision tolerances.
The surface quality of cold-rolled products is superior, there are no defects such as pitting, hot-pressed iron oxide, etc., and coils of different surface roughness (glossy or hemp) can be produced according to user requirements. Aesthetically appealing, thus ideal for manufacturing products that are used to attract consumer attention.
After cold rolling, the mechanical properties of the steel such as hardness, tensile strength, and yield strength are improved and more consistent.
It is possible to increase the steel's strength by up to 20% because of strain hardening.
Steel manufacturers are able to achieve a lower range of thickness than that of hot rolled steel coils, could obtain extremely thin strips that cannot be produced by hot rolling (up to 0.001 mm or less).
Low carbon steel is mainly used, which requires good cold bending and welding performance, as well as certain stamping performance.
Application
Automobile manufacturing, Home appliance, Precision Instruments, Aviation, Construction material, Industrial equipment and so on.
It can also be further processed as pickling, rolling hard coil, ordinary cold rolling, galvanizing (electric galvanizing, anti-fingerprint, hot-dip galvanized steel), aluminum zinc plating, tin plating, color coating, electrical steel (silicon steel sheet).
