performance

Performance: Studied experimentally under normal circumstances, the hot plate and its mechanical properties in engineering is no more think of, although there are certain work hardening heat pipes in the process of cold rolling, (but do not rule out strict in mechanical properties, that is need to discriminate), cold plate heat plate usually slightly high yield strength, surface hardness is higher, what specific needs to see the degree of cold plate annealing. But no matter how the strength of the annealed cold plate is higher than the hot plate.

Forming performance, because the performance of the hot and cold plate is not too much, so the influencing factors of the forming performance will depend on the difference of the surface quality, because the surface quality is better, so usually speaking with the material of the steel plate, cold plate than hot plate forming appearance effect is better.

Cold rolled strip is widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, canned food, etc. Cold rolled sheet steel is the abbreviation of common carbon structural steel cold rolled sheet, also known as cold rolled sheet, commonly known as cold plate, sometimes mistakenly written as cold tied sheet. Cold plate is made of ordinary carbon structural steel hot rolled steel strip, after further cold rolling into a thickness of less than 4mm steel plate. Due to rolling at room temperature, does not produce iron sheet, therefore, cold plate surface quality, high dimensional accuracy, coupled with annealing treatment, its mechanical properties and process properties are better than hot rolled thin steel sheet, in many fields, especially in the field of home appliance manufacturing, has gradually replaced hot rolled thin steel sheet.
