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

A |     (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)                    。    据媒体报道，近日，25岁的中国女留学生文文（化名）在赴韩国领取毕业证期间失联，她与家人最后一次联系是在8月19日。庆北警察厅25日表示，已抓获涉嫌杀害该女生A某（25岁）的30多岁男性B某，并正在进行调查。警方当天下午7时29分许在庆山市对B某执行拘留，并在庆山市河阳邑的B某住处发现A某遗体。
