2025年12月18日理想材料负责人段吉超表示 左下角是沃尔沃的车身热成型比例变迁图，热成型的比例从个位数一直上升到38%，后来几乎没有再突破了（再说个小知识，这38%中只有33% 是1500MPa以上超高强钢。因为，热成型不都是1500MPa以上，也有几百MPa的、局部吸能少量使用，后略）。 干货分享【热成型钢用量越大，车身越安全？】 之前在网络上经常看到类似的话，大概就是哪个车的热成型钢比例高，所以它一定更安全。恰恰在各个车企的发布会上，热成型钢又是曝光度很 高的点，大概是因为简单的观点，往往传播力更强。 最近，恰巧我在北京总部举办了"材料技术日"活动，被不少媒体朋友问到这个点，今天就简单分享下。 先说结论，我认为这句话不严谨、不正确。 1、「热成型钢的使用原因」 热成型钢的定义我们不赘述了，通常大家理解的大概是车身上强度高达1500MPa-2000MPa的钢材（其实有些冷冲压、冷辊压也能到这个级别， 此处略）。我们使用它的主要原因，确实主要是因为它的强度高。把它用在车身碰撞传力路径的安全结构件，可以起到防止碰撞时过度变形、入侵乘员生 存空间的作用。 2、「为什么车身热成型比例没有一直往上走？」 其实，严 ...
