Today, the Stainless Steel Kitchen Cabinets manufacturer will share the knowledge of hot and cold rolling of stainless steel.

Cold rolling: It is processed and rolled on the basis of hot-rolled stainless steel plate coils, generally in the process of hot rolling, pickling and cold rolling. Although the steel plate is heated during the processing because of rolling, it is still called cold rolling. Due to the cold rolling of hot rolling through continuous cold deformation, the mechanical properties are relatively poor and the hardness is too high. It must be annealed to restore its mechanical properties, and the unannealed is called a hard roll. Rolled hard rolls are generally used for products that do not require bending or stretching.

Its characteristics:

  1. Cold-rolled steel sheet has low toughness and high price due to a certain degree of work hardening;

  2. The surface of cold-rolled processing has no scale and good quality;

  3. The product made by cold deformation has high dimensional accuracy and good surface quality;

  4. Cold rolling is widely used in various industries, such as various cold stamping parts, cold rolled cold extruded profiles, cold coil springs, cold drawn wires, cold heading bolts, etc.

Hot rolling is relative to cold rolling, which is rolling below the recrystallization temperature, and hot rolling is rolling at a temperature above the recrystallization temperature.

Its characteristics:

  1. Toughness and surface flatness are poor, and the price is low;

  2. The temperature of hot rolling is similar to the temperature of forging;

  3. The hot plate is treated with hot-rolled surface with oxide scale, and the thickness of the plate is lower;

  4. Due to its production and production process, it is more in civilian use, such as kitchen utensils, general household appliances, etc.;

  5. Hot-rolled steel sheet, mechanical properties are far less than cold processing, second only to forging processing, but has good toughness and ductility.
