High quality best price A573 Gr 70 carbon steel plate sheet

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 A573 Gr 70 carbon steel plate sheet plate should be derusted before cutting.

Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). A573 Gr 70 carbon steel plate sheet, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.

After years of operation and accumulation, the company has formed an operation network covering major economic cities across the country, with a group of high-quality professional logistics technicians and management personnel, strong strength and stable logistics channels. The company's business operations include the loading and unloading of steel raw materials and finished materials, A573 Gr 70 carbon steel plate sheet warehousing, and freight transportation. Our logistics service business has passenger transportation, automobile and construction machinery inspection, logistics information management and operations.

The carbon content of A573 Gr 70 carbon steel plate sheet, hot rolled steel plate is slightly higher than that of cold rolled steel plate. Hot rolled steel plate has low hardness, easy processing and good ductility. Cold rolled steel plate has high hardness and is difficult to process, but it is not easy to deform and has high strength. The strength of hot-rolled steel plate is relatively low, the surface quality (oxidation finish) is low, but the plasticity is good, and it is generally medium thick plate.
