个人中心收藏查看我的收藏0有用+10播报讨论上传视频高强度汽车结构用钢是符合JIS G3134标准的高强度汽车用钢，由宝钢、武钢、梅钢等企业联合生产 [1] [3] [7]。该钢材具有≥420MPa的屈服强度和≥590MPa的抗拉强度，化学成分严格控制碳、锰等元素含量，主要应用于汽车构架、车轮及大梁等结构件制造 [1] [5] [7]。产品形态包含热轧卷板、冷轧板及酸洗板，表面处理工艺保障其成型加工性能 [2] [6-7]。2019年宁钢通过优化热轧工艺参数实现该材料的稳定量产 [4]。抗拉强度≥590MPa
屈服强度≥420MPa [1]
执行标准JIS G3134
用    途汽车结构件制造 [5] [7]
工艺类型热轧/冷轧/酸洗 [1-2] [6]
产    地宝钢/武钢/梅钢 [1] [3] [7]

目录
1工艺与性能2应用领域3生产商与研发4技术参数
工艺与性能
播报编辑采用热轧与冷轧复合工艺生产，部分产品经酸洗处理实现表面无氧化铁皮残留 [2] [5]。通过板坯加热质量改进和热轧温度控制技术，解决了高合金含量带来的表面橘皮、麻点等缺陷 [4]。材料厚度范围覆盖1.5-10.5mm，提供开平、分条等粗加工服务 [6]。化学成分控制指标包含C≤0.18%、Mn≤0.60%及P/S≤0.025%，保障焊接性能与成型延展性。材料机械性能达到延伸率≥19%，部分产品抗拉强度可达640MPa [1]。
应用领域
播报编辑该钢材主要应用于：汽车构架：包括车架纵梁、横梁等承载部件 [5] [7]车轮制造：用于滚型车轮的轮辋与轮辐组件 [3] [7]传动系统：涉及传动轴管、桥壳等动力传输部件 [7]工业制品：扩展至仓储设备等非汽车领域 [2]
生产商与研发
播报编辑宝钢与武钢联合生产的卷板宽度达1000mm，重量范围2至28吨 [2]。2019年3月，宁波钢铁通过组建专项团队突破热轧工艺窗口限制，实现新版的批量生产 [4]。梅钢生产的酸洗板卷采用无花无油表面处理技术，规格包含2.0mm、3.0mm等常用厚度 [6-7]。
