备注:拉伸试样为GB/T228.1 中的 P6试样(L0=80mmb0=20mm),取样方向平行于轧制方向(纵向
试样)。 2.对于 Gl产品,当公称厚度t<0.6mm 时,新后律长率晨小规定值允许下降2%,对于 GA
产品,当公称厚度t<0.6mm 时,断后伸长率小规定值允许下降 4%;当公称早度t20.60mm 时,断
后伸长率小规定值允许下 降 2%。3.n0值是在 10%~20%应变范围内计算得到的,当均匀伸长率小
于 20%时,应变范围为 10%至均匀伸长结束。

材料特性及典型应用
材料特性:微观组织是以铁素体为基础含有岛状马氏体,因此具备高强度和良好的成形性能;低屈强比、高BH潜力、高加工硬化指数和能量吸收能力;
适于做车身的拉伸成型部件(内、外),尤其是抗撞部件,
典型应用:应用于结构件、加强件和防撞件,比如地板横梁、座椅轨道、防撞杆、B柱及加强板,前纵梁等结构件。
