Feature

Because it is rolled at normal temperature and does not produce scale, the cold plate has good surface quality and high dimensional accuracy, and its mechanical properties and technological properties are superior to those of hot rolled steel sheet. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot rolled steel sheet.

Difference between hot rolled steel sheet

1)Different colors

The surface of hot-rolled plate is brown, and the color is inconsistent, or bai has du pattern without oil.

2)Different texture edges

The texture of cold-rolled plate is delicate and smooth, and the edge is neat

The surface texture of hot-rolled plate is rough, the shape is not regular for cold rolling, and sometimes the edges are irregular.

3)Different specifications

Cold-rolled plates are generally thin with a thickness of less than 3.0mm (except for customization), silvery white is galvanized plate, and color is color coated plate.

Hot-rolled plates are generally over 1.5mm (except customized ones), the thinnest is not less than 1.0, and they have temperature-dependent oxidation patterns.

4)Different hardness

Cold-rolled plate has high hardness and is relatively difficult to process, but it is not easy to deform and has high strength; Hot rolled steel plate has low hardness, easy processing and good ductility.

5)Different production processes

Cold rolling is carried out at normal temperature, the cold-rolled steel plate has better strength and the cold-rolled thickness is relatively small; Hot-rolled steel plate is rolled at high temperature, which has better ductility, and hot-rolled steel plate can have larger thickness.

Application

Cold rolled steel sheet has good properties, that is, cold-rolled strip steel and steel plate with thinner thickness and higher precision can be obtained by cold rolling, with high flatness, high surface finish, clean and bright surface of cold-rolled plate, easy coating processing, many varieties and wide applications, and also has the characteristics of high stamping performance, no aging and low yield point, so cold-rolled plate has a wide range of applications, mainly used in automobiles, printed iron drums, buildings, building materials, bicycles and so on.

Application

As China metal materials industry leading enterprises, the national steel trade and logistics "Hundred good faith enterprise",China steel trade enterprises, "Top 100 private enterprises in Shanghai”. Shanghai Zhanzhi industry Group Co., Ltd.,(shorted to Zhanzhi Group) takes the" Integrity, Practicality, Innovation, Win-Win " as its sole operation principle, always persist in putting the customer demand in the first place.
