For a long time, a number of excellent steel production enterprises in China have devoted themselves to the production of materials for aerospace use. For example, over the years, HBIS has assisted manned spaceflight, lunar exploration projects, and satellite launches. The “Aerospace Xenon” developed and produced by HBIS has been used as a satellite attitude propellant, filling the domestic gap, breaking the 40-year overseas monopoly, and boosting China’s “Shihshi 13 Satellite” successfully flew into the sky. TISCO continues to research and develop new aerospace materials and create high-quality aerospace steel products. TISCO stainless steel cold and hot-rolled products and electromagnetic pure iron are used in the “Chang’e Lunar Exploration Project” lunar probe, “Shenzhou” series spacecraft, and “Long March” series transportation Rockets, “Tiangong-1″ target aircraft, etc. The products developed by Panchang Special Steel Plant were successfully applied to the “Shenzhou 11″ spacecraft. Northeast Special Steel has provided a variety of high-end special steel products for “Tianzhou 1″ and its carrier rocket “Long March 7″. Hunan Valin Cable Co., Ltd. has provided hundreds of high-temperature ignition cables for the “Long March” series of rockets. From “Shenzhou 1″ to “Shenzhou 11″, the launch ignition cables are all from Valin.
