cold rolled coils and cold rolled strips
Now the steel industry is developing better and better. The former iron products are easy to rust and easy to corrode and not durable. The high quality cold rolled steel coil china is also slowly replacing the original iron products. The cold rolled coils have good surface quality, high smoothness and are not easily oxidized. Business welcome. Moreover, many consumers are entangled in the purchase process. What is the difference between cold rolled coil and cold rolled strip? Let’s talk about their differences today:
Cold rolled coils are often called cold rolled coils. Due to the cold work hardening caused by continuous cold deformation, the strength and hardness of the rolled hard rolls are increased, and the toughness index is lowered. Therefore, the punching performance is deteriorated only for the parts that are simply deformed.
The cold-rolled steel sheet is processed from a hot-rolled sheet at a normal temperature. Although the steel sheet is heated during the processing because of rolling, it is called cold rolling. Since the cold rolling of the hot rolling through the continuous cold deformation is relatively poor in mechanical properties, the hardness is too high. It must be annealed to restore its mechanical properties. The unrolled hard rolled coil is usually used for products that do not require bending.
The cold-rolled coil is produced by rolling hot-rolled coils at room temperature below the recrystallization temperature, including plates and coils. Many domestic steel mills such as Baosteel, Wuhan Iron and Steel, and Anshan Iron and Steel can produce. The steel plate, also called the steel plate, is also called the steel plate, which is called the steel plate or the flat plate.
Cold rolled coils are used in a wide variety of applications such as automotive manufacturing, electrical products, rolling stock, aviation, precision instruments, and food cans. Cold-rolled steel sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet. Also known as cold-rolled coil, cold plate is sometimes mistakenly written as cold-rolled sheet.
