"As China's largest high-performance industrial wire and special steel manufacturer, HBXG Special Steel Technology Group's users are mainly concentrated in the fields of automobiles and mechanical parts.
HBXG has always been committed to the research and development of high-performance metal materials such as high-strength cold-formed steel and product customization, and has developed close cooperation with downstream industries to continue to provide parts manufacturers with high-quality products at competitive prices.
In recent years, HBXG has aimed at product innovation and foreign substitution, targeting international high-end wire products, serving high-end customers in the industry, focusing on the professional production of industrial materials, special steel materials, and high-end wire rods. Through independent research and development, joint development and implementation of quality research, automotive More than 20 products including fasteners, high-strength weathering steel, bridge suspension steel, and industrial pure iron have realized import substitution.
The Q series cold formed steel products developed by HBXG have stable surface crack control below 0.05mm, which is far lower than the current national standard requirement of 0.10mm. They are applied to major domestic and foreign automobiles and construction machinery; chromium-molybdenum cold-formed steel is used The high-strength bolts produced are used in automobile power systems (engine cylinder head bolts, connecting rod bolts and flywheel bolts) and other parts with the highest technical content and the most critical parts. There are only two manufacturers of this type of steel in China. . In the field of automotive applications, HBXG has successfully passed the certification of 38 well-known domestic and foreign automotive OEMs including Honda, General Motors, Ford, Hyundai Motor, and SAIC, and has been recognized and recognized by high-end customers in the automotive manufacturing field.
In the production of other high-performance cold-formed steel products, many HBXG products have also achieved domestic firsts. The first paint-free bridge bolted by weathering steel in China is the Yarlung Zangbo River Zangmu Bridge, which is located in high-cold and high-altitude areas. Sparsely populated and inconvenient to maintain. The bridge has a long span and is free of painting as a whole, and independent welding cannot meet the requirements for installation and painting. HBXG and the China Academy of Railway Sciences have jointly developed the XG835NH product for high-strength weathering steel bolts. The finished bolt strength meets 10.9 bolts. It is required, and the corrosion resistance index I>6.5, and the overall coating-free use fills the gap in domestic high-strength weathering steel bolt products. It is of great practical significance to promote the healthy and sustainable development of China's steel industry and bridge corrosion protection industry.
