* Product Applications
Cold rolled steel has good performance, that is, through cold rolling, you can get thinner and more accurate cold rolled strip and steel plate, high straightness, high surface finish, cold rolled plate surface clean and bright, easy to carry out coating processing, a wide variety of uses, and also has high stamping performance and non-aging, low yield point, so cold rolled plate has a wide range of uses, mainly used in automotive, printing barrels, construction, building materials, bicycles and other industries, but also the production of organic coating steel plate is the best choice of materia.
* Product characteristics
1、Appearance and surface quality
Because the cold plate is hot plate after the cold rolling process, and cold rolling at the same time will be some surface finishing, so the cold plate in the surface quality (such as surface roughness and so on) than the hot plate, so if there are high requirements for the product after the painting and other coating quality, generally choose the cold plate, another hot plate and pickled plate and pickled plate, pickled plate surface due to pickled so into the normal metal color, but not cold rolled So the surface is still not cold plate high, not pickled plate usually surface oxidation layer with, black, or the presence of iron tetroxide layer, commonly known as fire baked similar, and if the storage environment is not good, usually with some embroidery.
2, performance
In general, the hot plate and cold plate in the engineering of its mechanical properties are considered no difference, although the cold plate in the cold rolling process there is a certain degree of hardening, (but does not exclude the case of strict requirements for mechanical properties, that need to be treated differently), cold plate is usually slightly higher than the yield strength of the hot plate, the surface hardness is also higher, how specific need to look at the degree of cold plate annealing.
3, forming performance
due to the basic performance of the hot and cold plate is not too much, so the forming performance of the factors affecting the difference in its surface quality, due to the surface quality of the cold plate to be good, so generally speaking, the same material steel plate, cold plate than the hot plate forming appearance effect is better.3, forming performance.
As the performance of hot and cold plate is basically not too much, so the forming performance of the factors affecting the difference in its surface quality, due to the surface quality of the cold plate to be good, so generally speaking, the same material steel plate, cold plate than the hot plate forming appearance effect is better.
