CR5 is the designation for cold-rolled steel used in automobiles, specifically referring to cold-rolled steel coils for automotive applications. Below is an introduction to related content: 1. Specific meaning: CR3 is 0.5*1250*C, CR4 is 0.65*1190*C, and CR5 is 0.65*1565*C, where 0.65 represents the thickness, 1565 is the standard width, and C stands for coil. 2. Steel rolling: Steel rolling is the pressure processing process that changes the shape of steel ingots and billets between rotating rollers. The purpose of steel rolling, like other pressure processing methods, is twofold: on one hand, to achieve the desired shape, such as steel plates, strips, wires, and various types of steel; on the other hand, to improve the internal quality of the steel.
