Over the years, the company has established a standard of A709 grade 100W bridge steel plate steel products pre-sale, in sale and after-sale service, which meets customers' needs in all aspects and in the whole process, so that our products and services are deeply trusted by customers, and has established a long-term cooperation and mutual benefit relationship with customers. The company adheres to A709 grade 100W bridge steel plate quality surpervision, comprehensively implements quality management, strictly controls the whole process of product from contract signing to after-sales service.
Alloy 42crmo is used to manufacture forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, pressure vessel gears, rear axles, loaded connecting rods and spring clips. In addition, this steel A709 grade 100W bridge steel plate can also be used for oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines.
As a new type of coil material, compared with the traditional steel coil, A709 grade 100W bridge steel plate, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.
A709 grade 100W bridge steel plate, The hardened wear-resistant plate is quenched and hardened as a whole, and the martensite in the metallographic structure improves the overall hardness, and the micro hardness and macro hardness are basically the same. Cemented carbide and T10, even if the macroscopic hardness of T12 steel and cemented carbide after quenching is basically the same, the wear resistance of cemented carbide is much higher than that of T12 steel, because there are a large number of carbides in cemented carbide .
