sa573 gr 70 structural carbon steel BBN steel supply high quality carbon plate

The company adheres to the principle of integrity, standardization and efficiency, wins the market with technology, gains reputation with creative services, and wholeheartedly provides customers with high-quality sa573 gr 70 structural carbon steel, efficient and fast services. Facing the future, adhere to independent innovation.

The cold rolled sheet does not produce scale because it is rolled at room temperature. Therefore, the surface quality of cold plate is good and the dimension precision is high. In addition, the mechanical and technological properties of cold rolled coil are better than that of hot-rolled steel sheet. In many fields, especially in the field of home appliance manufacturing, it has gradually replaced hot-rolled steel sheet, sa573 gr 70 structural carbon steel.

BBN company has steel plates production workshops and warehouses with a total area of more than 500,000 square meters, and the total inventory of various types of steel exceeds 1 million tons. Relying on world-leading processing equipment and storage facilities, the company has strong steel production and processing capabilities, comprehensive logistics and logistics services, ensuring that it can efficiently complete more than 1 million tons of hot rolled plates processing business each year.

The allowable working temperature of boiler steel plate is generally below 475 ℃, which can't meet the needs of high temperature working condition. Chromium molybdenum steel is one of the common steels for sa573 gr 70 structural carbon steel pressure vessels, which is widely used in various hydrogenation units and reforming units in oil refining and chemical industry. Therefore, on the basis of common sa573 gr 70 structural carbon steel carbon steel, alloy elements such as Cr Mo V are added, which has excellent hydrogen corrosion resistance and good high temperature strength, It is the material of high temperature and high pressure vessel shell and head.
