Product Description

Cold-rolled coil is produced from hot-rolled coil at room temperature and below the recrystallization temperature. Products delivered in sheet form are called steel plates (also known as box plates or plates), while those delivered in long lengths and wound into coils are called steel strips (also known as coil plates).

Production Process:
Since no heating is involved, cold rolling eliminates defects such as pitting and scale that may occur in hot rolling. The resulting surface quality is excellent, with high surface finish. Furthermore, cold-rolled products offer high dimensional accuracy, and their properties and microstructure can be tailored to meet specific requirements, such as electromagnetic performance and deep drawability.

Performance:
Primarily made of low-carbon steel, cold-rolled coils exhibit good cold bending and welding properties, along with certain stamping performance.
SPCC is a commonly used grade for cold-rolled carbon steel sheet and strip.

SPCC Specification & Features of Cold-Rolled Steel Plate:

Cold-rolled steel plate offers more precise thickness, smooth and aesthetically pleasing surface, as well as superior mechanical properties, particularly in terms of machinability.

The maximum thickness of cold-rolled steel plate typically ranges below 0.1–8.0 mm. In most factories, the thickness of cold-rolled steel plate is less than 4.5 mm. The minimum thickness and width are determined by the equipment capacity and market demand of each plant.

Cold rolling requires higher power consumption and results in lower rolling efficiency. To eliminate work hardening during the rolling process, intermediate annealing is often necessary, leading to higher production costs. However, cold-rolled steel features a bright surface and high quality, making it suitable for finished product processing. As a result, cold-rolled steel is widely used across various industries.

SPCC Specification

Features of cold-rolled steel plate:
1, Cold rolled steel plate thickness more accurate, smooth surface, beautiful, but also has superior mechanical properties, especially machining performance.
2. The maximum thickness of cold-rolled steel plate is less than 0.1-- 8.0mm, such as the thickness of cold-rolled steel plate in most factories is less than 4.5mm;The minimum thickness and width are determined according to the equipment capacity and market demand of each plant.
3, cold rolled steel mill power, low rolling efficiency, and the rolling process in order to eliminate the work hardening have to carry out intermediate annealing, so the cost is higher, but cold rolled steel surface bright, good quality, can be used to process finished products, cold rolled steel is widely used.
