高级高强度汽车薄板钢的分类和特性

[中文适用范围]： 该 SAE 推荐实践定义了各种等级的连铸高强度钢板并建立了机械性能范围。这些钢板可以在汽车制造过程中成型@焊接@组装和涂漆。它们可以指定为热轧或冷轧板材。此外，它们可以进行涂层（热浸镀锌@热浸镀锌@和电镀锌）或不涂层。并非所有强度@尺寸和涂层的组合都可以在市场上买到；详情请咨询您的钢材供应商。 [外文原描述]： This SAE Recommended Practice defines various grades of continuously cast high-strength sheet steels and establishes mechanical property ranges. These sheet steels can be formed, welded, assembled and painted in automotive manufacturing processes. They can be specified as hot-rolled or cold-rolled sheet. Furthermore, they can be coated (hot-dipped galvanized, hot-dipped galvannealed, and electrogalvanized) or uncoated. Not all combinations of strength, dimensions and coatings may be commercially available; consult your steel supplier for details.
