Several common cold rolled sheet steels and their uses

Cold rolled ordinary thin steel plate: cold rolled from ordinary carbon structural steel or low-alloy structural steel. The surface quality of the cold-rolled sheet is better. Has good stamping properties. It is required to ensure that the cold bending and cup tests are qualified, and it is often used in industries such as automobiles and as raw materials for plated sheets.

Cold-rolled high-quality steel sheets: mainly include various high-quality steel cold-rolled sheets, the most commonly used are carbon structural steel sheets, especially cold-rolled steel sheets for deep drawing.
Cold-rolled steel sheet, with smooth surface and excellent processing, is used in home appliances such as automobiles, refrigerators, and washing machines, as well as industrial equipment and various building materials. With the development of economy, cold-rolled steel sheet has been called an essential material in modern society.
Application areas:
Cold-rolled strips are widely used, such as automobile manufacturing, electrical products, rolling stock, aviation, precision instruments, and canned food.
Cold-rolled sheet is the abbreviation of ordinary carbon structural steel cold-rolled sheet, also known as cold-rolled sheet, commonly known as cold-rolled sheet, and sometimes mistakenly written as cold-rolled sheet. The cold plate is a hot-rolled steel strip of ordinary carbon structural steel, which is further cold-rolled into a steel plate with a thickness of less than 4mm. Due to rolling at room temperature, no scale is produced, therefore, the cold plate has good surface quality and high dimensional accuracy, coupled with annealing treatment, its mechanical properties and process properties are better than hot-rolled steel sheets, in many fields, especially In the field of home appliance manufacturing, it has gradually replaced hot-rolled sheet steel.

The difference between cold rolled steel and hot rolled steel

What kind of performance does carbon steel coil have

Although stainless steel plates account for a relatively small proportion of world steel consumption, they are still vital to specific manufacturing industries such as the energy and food processing markets. At present, the global consumption of stainless steel plate materials is continuously increasing.

Production process of welded steel pipe

The development of steel pipe production technology began with the rise of bicycle manufacturing, the development of petroleum in the early 19th century, the manufacture of ships, boilers, and aircraft during the two world wars, the manufacture of thermal power boilers after the Second World War, the development of the chemical industry, and The drilling and transportation of oil and natural gas have strongly promoted the development of the steel pipe industry in terms of variety, output and quality.

Steel prices have risen by more than a thousand steel companies generally turn losses into profits

Since the first half of last year, steel prices have begun to recover thanks to a series of measures such as supply-side reforms and elimination of backward production capacity. Taking rebar as an example, the average price on March 9 last year was 2475 yuan/ton, and on March 9 this year, it has risen to 3852 yuan/ton, an increase of 35%.

China Steel Association: Steel prices in the domestic market continued to rise slightly in September

According to data from the China Iron and Steel Association, in September, the domestic steel market demand was strong, and steel prices continued to rise. Affected by the rapid release of steel production capacity, pressure on the supply side has risen, and the price increase of steel has narrowed.
