Activity Description
The production process of cold-rolled hard coils includes pickling and cold rolling of hot-rolled coils, covering energy consumption, material consumption, waste treatment, and environmental emissions required during the production process.
Process Description
Cold-rolled hard coil is a type of steel coil processed by cold rolling, falling under the category of cold-rolled products such as cold coils, cold plates, and cold-rolled strip steel. It is produced from hot-rolled steel coils that are pickled to remove oxide scale and then subjected to cold rolling. The 20Cr13 stainless steel cold-rolled hard coil is a martensitic stainless steel product, characterized primarily by high carbon and high chromium content. This stainless steel contains approximately 13% chromium and 0. With 2% carbon, this chemical composition provides good corrosion resistance and high strength. After cold rolling, the hardness and strength of 20Cr13 stainless steel are further enhanced while maintaining favorable workability. Cold-rolled hard coils of 20Cr13 stainless steel are primarily used in applications requiring corrosion resistance and high strength, such as cutlery, medical instruments, springs, valves, and certain chemical processing equipment.

Technology comment
Using hot rolled steel coils as raw material, after pickling to remove the oxide scale, continuous cold rolling is carried out to produce hard-rolled coils. Due to cold work hardening caused by continuous cold deformation, the strength and hardness of the hard-rolled coils increase, while toughness and ductility decrease. Therefore, their stamping performance is relatively poor, and they can only be used for parts requiring simple deformation.
