cold rolled steel plate description

cold rolled steel plate description

cold rolled steel plate is produced by cold rolling process, referred to as cold plate. The thickness of cold-rolled plate is generally between 0.1 and 8.0mm, and the thickness of cold-rolled plate produced by most factories is below 4.5mm. The thickness and width of cold-rolled plate are determined by the equipment capacity of each factory and the market demand.Compared with hot rolled steel plate, cold rolled steel plate thickness is more accurate, and the surface is smooth and beautiful.

cold rolled steel plate application 

Cold-rolled strip is used in a wide range of applications, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, food cans and so on. Cold-rolled sheet steel is short for cold rolled plate of ordinary carbon structural steel, also known as cold rolled plate, commonly known as cold plate, sometimes mistakenly written as cold tie plate. 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. Because of rolling at normal temperature, no oxide sheet is produced, so the surface quality of cold plate is good, the dimensional precision is high, coupled with annealing treatment, its mechanical properties and technological properties are better than hot rolled sheet steel, in many fields, especially in the field of household appliances manufacturing, has gradually replaced hot rolled sheet steel with it.

cold rolled steel sheet classification

cold rolled steel sheet Classification

1、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. The requirements to ensure that the cold bending and cup test qualified, often used in automotive and other industries and coating plate raw materials.
2、Cold rolled high quality steel sheet: mainly includes a variety of high quality steel cold rolled sheet, the most commonly used is carbon structure steel sheet, especially with deep stamping cold rolled steel sheet, is made of low carbon high quality steel 08Al cold rolled sheet, steel plate according to the surface quality is divided into three groups; Ⅰ, Ⅱ, Ⅲ, respectively said that the special senior, senior, higher finishing surface, according to the drawing level is divided into ZF, HF, F (on behalf of the most complex drawing for punching, very complex, complex parts), according to the allowable deviation of steel plate thickness, and is divided into A, B two level precision, widely used in the automobile tractor industry.
3、Cold rolled steel plate, smooth surface, excellent processing, used in automobiles, refrigerators, washing machines and other household appliances, as well as industrial equipment, all kinds of building materials. With the development of economy, cold rolled steel plate has been called the modern society must material. Classification of cold rolling products: hot pickling, hard rolling, ordinary cold rolling, galvanized (electric galvanized, fingerprint resistant, hot galvanized), aluminum zinc plating, tin plating, color coating, electrical steel (silicon steel sheet), etc.
