A572 gr42 steel plate is a kind of main precision steel structure and normalizing steel. , ASTM A572 gr42, 50, 55, 60, 65 is a kind of high strength low alloy steel plate, which is widely used in factory construction, general buildings and various construction machinery, such as mining and various construction drilling rigs, electric shovels, electric wheel dump trucks, mining trucks, excavators, loaders, bulldozers, various cranes, hydraulic supports, mining machinery and other structures.GB Q345B grade steel,BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.After twenty years of efforts, the company has completed the steel plates production process and complete testing equipment from smelting, rolling, drawing, heat treatment to full material Large-scale production, intensive, and unremitting research and development and innovation make our products maintain long-term vitality In early 2008, the company established the Ministry of foreign trade, and our steel plate products are now exported to the South Asia, the Middle East, Europe and the United States,GB Q345B grade steel.GB Q345B grade steel,45# steel is widely used in mechanical manufacturing, and its mechanical properties are very good. But 45# steel is a kind of medium carbon steel, the quenching property is not good, 45# steel can be hardened to HRC42 ~ 46. Therefore, if the surface hardness is required, and the superior mechanical properties of 45# steel are expected to be exerted, the surface of 45# steel is often carburized and quenched, so that the required surface hardness can be obtained.GB Q345B grade steelRespect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.GB Q345B grade steel
