Brand: Q225-GB912-89 The main producing areas are: Baosteel, Angang, Bensteel, Wuhan Iron and Steel, Handan Iron and Steel, Baogang, Tang Steel, Lian Steel, Jinan Steel and so on
Cold-rolled ordinary sheet steel: cold rolled by ordinary carbon structural steel or low alloy structural steel. The surface quality of cold rolled sheet is better. It has good stamping performance. It is required to ensure that the cold bending and cup test is qualified, which is often used as raw materials for automotive industries and coated plates.
Cold-rolled high-quality sheet steel: mainly includes a variety of high-quality steel cold-rolled sheet, the most commonly used is carbon structure steel, especially with deep stamping cold-rolled sheet steel, is made of low carbon high-quality steel 08Al cold-rolled sheet, steel plate is divided into three groups according to surface quality; Ⅰ, Ⅱ, Ⅲ, respectively, that is especially advanced, advanced, higher finishing surface, according to the drawing level is divided into ZF, HF, F (representing the most complex, very complex, complex parts for punching drawing). According to the allowable deviation of the thickness of the steel plate, it is divided into A and B two levels of accuracy, and is widely used in the automobile tractor industry.
Cold-rolled steel plate: smooth surface, excellent processing, used in automobiles, refrigerators, washing machines and other home appliances, as well as industrial equipment, a variety of building materials. With the development of economy, cold-rolled steel plate has been called a necessary material in modern society. Classification of cold rolling products: hot pickling, hard rolling, ordinary cold rolling, galvanizing (electric galvanizing, fingerprint resistance, hot galvanizing), aluminum plating, tin plating, color coating, electrical steel (silicon steel sheet), etc.
