Cold-rolled sheet

Cold rolled sheet (English name: cold rolled sheet) is a product made of hot-rolled coil as raw material and rolled below the recrystallization temperature at room temperature. It is mostly used in automobile manufacturing, electrical products, etc. Cold rolling is rolling at a recrystallization temperature, but it is generally understood as rolling using materials that are rolled at room temperature.

1. Due to the lack of heating in 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. Moreover, the dimensional accuracy of cold-rolled products is high, and the performance and structure of the products can meet some special use requirements, such as electromagnetic properties, deep drawing properties, etc.

2. Specifications: The minimum thickness is 0.2-4mm, the width is 600-2 000mm, and the length of the steel plate is 1 200-6 000mm.

3.牌号：Q195A-Q235A、Q195AF-Q235AF、Q295A(B)-Q345 A(B); SPCC、SPCD、SPCE、ST12-15; DC01-06

4. Performance: Mainly using low carbon steel grades, which require good cold bending and welding performance, as well as certain stamping performance.

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, which is sometimes miswritten as cold-rolled plate. The 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. Because it is rolled at room temperature, no iron oxide scale is produced, therefore, the surface quality of the cold plate is good, the dimensional accuracy is high, coupled with the annealing treatment, its mechanical properties and process properties are better than the hot-rolled thin steel plate, in many fields, especially in the field of home appliance manufacturing, it has been gradually replaced by hot-rolled thin steel plate.
