The thickness of SM570 carbon steel plate sheet from BBN

SM570 carbon steel plate sheet, Q960 steel plate can be used for cold working, bending and cutting. During gas cutting, cracks will not occur even without preheating. When preheating, Q960 quenched and tempered steel should be processed below tempering temperature. Compared with ordinary steel, Q960 quenched and tempered steel has good corrosion resistance, high hardness and good wear resistance.

After the steel plate is produced from the original factory, it will pass through a series of transportation and storage links and then be delivered to the processing workshop. During this period of time, the steel plate surface will contact with the air continuously, which will inevitably produce a layer of oxide skin. The oxide skin is a difficulty in the treatment process. It has high melting point, is not easy to burn and dissolve, increases preheating time, reduces cutting speed. Therefore, the surface of the SM570 carbon steel plate sheet plate should be derusted before cutting.

Steel plate is divided into rolling, hot rolling and cold rolling. The width of the thin plate is 500 ~ 1500 mm; the width of the thick plate is 600 ~ 3000 mm. Thin plates are classified according to steel types, including ordinary steel, steel, alloy steel, spring steel, stainless steel, tool steel, heat-resistant steel, SM570 carbon steel plate sheet, bearing steel, etc .; according to use, there are ship plates, pressure vessel plates, atmospheric corrosion-resistant steel plates, bulletproof steel plate.

As of early November, China's pig iron output was 24.662 million tons. Although the output of pig iron has declined due to the suspension of production during the heating season, the rate of decline has been slow, still at a high level of over 24.5 million tons. This is 13.5% higher than the same period last year, which makes coke demand good, and the six rounds of increase have landed smoothly. Some areas such as Shandong even appear out of stock.
