Cold rolled steel plate
Cold rolled coil is made by rolling hot rolled coil at room temperature below the recrystallization temperature. Cold rolled coil includes plates and coils. Steel plates delivered in single sheets are called steel plates, also called box plates or flat plates; steel strips delivered in long strips in coils are called steel strips, also called coils.
Product Parameters
Product Name | SPCC/SPCC/SPCD/SPCE Cold Rolled Steel Plate |
Production Process | Hot Rolling, Cold Rolling |
Material Standards | AISI, ASTM, ASME, DIN, BS, EN, ISO, JIS, GOST, SAE, etc. |
Width | 45mm-2200mm |
Length | Custom Size |
Thickness | 0.2mm-3mm |
Delivery Conditions | Rolling, Annealing, Quenching, Tempered or Standard |
Surface Process | Ordinary, Wire Drawing, Laminated Film |
Cold rolling definition
It is rolling under recrystallization, but it is generally understood as rolling using room temperature rolled materials. Aluminum cold rolling is divided into plate rolling and foil rolling. Plates with a thickness of 0.15~ or more are called plates, and foils with a thickness of 0.15~ or less are called foils. Europe and the United States mostly use 3~6 continuous rolling mills as cold rolling equipment.
Since there is no heating during the production process, there are no defects such as pitting and iron oxide scale that often occur in hot rolling, and the surface quality is good and the finish is high. In addition, the dimensional accuracy of cold-rolled products is high, and the performance and organization of the products can meet some special use requirements, such as electromagnetic properties, deep drawing properties, etc.
Specifications: thickness is 0.2-4mm, width is 600-2 000mm, and steel plate length is 1 200-6 000mm.
Grade: Q195A-Q235A, Q195AF-Q235AF, Q295A(B)-Q345 A(B); SPCC, SPCD, SPCE, ST12-15; DC01-06
Performance: Mainly low carbon steel grades, requiring good cold bending and welding performance, as well as certain stamping performance.

Application
Cold-rolled sheet and strip,It has a wide range of uses, such as automobile manufacturing, electrical products, locomotives and rolling stock, aviation, precision instruments, food canning, etc. Cold-rolled thin steel plate is the abbreviation of ordinary carbon structural steel cold-rolled plate, also known as cold-rolled plate, commonly known as cold plate, and sometimes mistakenly written as cold-rolled plate. Cold plate is made of ordinary carbon structural steel hot-rolled steel strip, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Since it is rolled at room temperature and does not produce iron oxide scale, the surface quality of cold plate is good and the dimensional accuracy is high. In addition, after annealing, its mechanical properties and process performance are better than hot-rolled thin steel plate. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled thin steel plate.
