China achieves mass production of advanced specialty steel across multiple sectors_我的网站

一 |     (ECNS) -- China has successfully achieved the independent mass production of various high-end specialty steels, securing domestic supply chains across marine, aerospace, and electronics sectors.    By manipulating atomic structures to prevent brittleness and corrosion, researchers have developed high-performance steel for offshore wind turbines that allows for thinner plates and reduced alloy usage. This breakthrough is part of a newly established research-to-production system covering deep-sea, shipbuilding, and aerospace fields.    Key innovations include a 0.07mm-thick steel with high strength and ductility used in integrated circuit (IC) substrates and 5G receivers, and low-expansion steel for large aircraft molds. This year, seven new high-end steel types achieved major breakthroughs, with specialized steels mass-produced for electric vehicles, humanoid robots, and energy storage.    To support this high-end transition, China’s steel industry has accelerated smart upgrades, boasting three global “Lighthouse Factories” and 38 benchmark intelligent manufacturing plants.    (By Intern Lin Qiaochu, Zhang Dongfang)                    。    记者从广铁集团了解到：受粤北、湘南等地持续强降雨影响，部分途经京广京九铁路普速列车今天（4月21日）继续停运。　　持续强降雨发生后，铁路部门于今天（21日）12时前，对途经京广铁路韶关境内普速列车继续采取停运和折返运行措施，以确保列车和旅客安全；并将于21日10时至18时，停运部分途经京九铁路普速列车。
