What is Q460E

Q460E high-frequency welded steel pipe is a high-strength low-alloy structural steel pipe, with the characteristic of high strength, low temperature and strong impact toughness, the manufacturing process is more difficult. In recent years, China has overcome a number of technical problems, broken through the barrier of high-grade high-frequency welded pipe products under low temperature impact toughness is difficult to achieve high quality standards and unstable weld quality, which helps to obstacles to new product -40 ° C to reach the weld impact energy greater than average level of 100 joules, fully meet the requirements of an average of not less than 34 joules actual project proposed, and the other physical and chemical properties are in full compliance with the relevant standards and special technical requirements. The products have a bright future in the cold northern and southern power grids recent snow disaster-prone, UHV transmission line construction and construction steel structure areas with special requirements.
