摘　　要：介绍了我国高强度汽车用钢板的二次加工脆化行为及试验方法，通过修47GB／T24173，提升了二次加工脆化试验规范性和可操作性。推动国内汽车冷轧板生产企业与乘用车制造企业均不同程度采用或引用了这一标准，在加速汽车零部件国产化替代进口选材供料认证中发挥重要作用，取得了显著的经济和社会效益。This paper introduces the secondary work embrittlement behavior and test method for high strength automobile steel plate, through the revision of GB/T 24173, enhance the secondary work embrittlement behavior test normative and maneuverability. Promote domestic automobile manufacture enterprise and car manufacturers using or reference the standard, accelerating car parts localization replace imported material feeding certification plays an important role, has obtained the remarkable economic and social benefits.
