Embodiment 1
[0030] Cold-rolled stamping steel 1 with plane isotropy and excellent yield strength of 180MPa. The raw materials of cold-rolled stamping steel are: C: 0.0050%, Mn: 0.20%, ALs: 0.04%, Nb: 0.010%, Si: 0.03%, P: 0.010%, N: 0.001%, Ti: 0.006%, and the balance is Fe and unavoidable impurities; the cold-rolled stamping steel 1 is processed through slab heating, high-temperature rolling, cooling coiling, and cold rolling. , continuous annealing, and smoothing are prepared in six steps, among which,
[0031] 1) During the slab heating process, the soaking temperature of the slab is 1280°C;
[0032] 2) During the high-temperature rolling process, the rolling starts at 1100°C, the finishing temperature of hot rolling is 910°C, and the rolling thickness is 3.5mm;
[0033] 3) During the cooling and coiling process, the steel plate is cooled to 720°C by spraying water for coiling;
[0034] 4) During the cold rolling process, the steel coil is naturally cooled to 35°C, uncoiled and pickl...
Embodiment 2
[0039]Cold-rolled stamping steel 2 with excellent plane isotropic yield strength of 180MPa. The raw materials of cold-rolled stamping steel are: C: 0.0040%, Mn: 0.30%, ALs: 0.02%, Nb: 0.020%, Si: 0.013%, P: 0.015%, N: 0.002%, Ti: 0.008%, and the balance is Fe and unavoidable impurities; The five steps of rolling and high-temperature coiling are prepared, among which,
