Mechanical properties of steel structural bolts, international market analysis of high-strength bolts by Huayong steel structure
Mechanical properties of steel bolts, steel Tohmatsu analysis of the international market of high-strength bolts. Yongnianhua Yongqiang high-strength bolts are popular in Hebei, and Yongnian Huayong high-strength bolts are popular and are exported to the United States and Western European countries. Customers are so convinced of our products, there must be a reason for this. Steel structure bolts are made of high-strength steel, or bolts that require a large pre-tightening force, all can be called high-strength bolts. Steel structure high-strength bolts are mostly used for the connection of bridges, rails, high-pressure and ultra-high-pressure equipment. This type of bolt breakage is mostly brittle fracture. High-strength bolts used in ultra-high-pressure equipment require a large amount of prestress to ensure the seal of the container. Steel bolts are actually two types, friction type and pressure bearing type. The criterion for the shear strength of high-strength friction type bolts is that the shear force caused by the design load does not exceed the frictional force; the high-strength bolts of the pressure type are not protected by the shaft. Shears or panels are not crushed as a design criterion. At present, most foreign steel structure bolts are imported from China, and it is expected that demand will continue to increase in the next 10 years, and the outlook is optimistic. Handan Huayong Standard Parts Co., Ltd. sales center specializes in producing steel structural bolts and high-strength bolts. The product specifications and quality assurance are welcome.
