摘要：
本发明公开了一种快速、减薄冲压加工的新能源汽车电池壳用钢及生产方法，所述电池壳用钢化学成分组成及其质量百分含量为：C：0.0030～0.0060%，Mn：0.10～0.20%，Si≤0.03%，Als：0.050～0.090%，Ti：0.050～0.070%，P≤0.015%，S≤0.012%，N≤0.0040%，余量为Fe及不可避免的杂质；所述生产方法包括炼钢、连铸、热轧、卷取、冷轧、连续退火、平整工序。本发明方法生产的快速、减薄冲压加工的新能源汽车电池壳用钢可以适应快速冲压和减薄冲压的加工要求，克服了低碳类电池壳钢成形性能差的问题，生产工艺控制要点明确，具有较好的实施性，且生产成本较低。
摘要（英）：

The invention discloses quick and thinning stamping processing new energy automobile battery shell steel and a method for producing the same. The quick and thinning stamping processing new energy automobile battery shell steel comprises chemical components including, by weight, 0.0030-0.0060% of C, 0.10-0.20% of Mn, less than or equal to 0.03% of Si, 0.050-0.090% of Als, 0.050-0.070% of Ti, less than or equal to 0.015% of P, less than or equal to 0.012% of S, less than or equal to 0.0040% of N, the balance Fe and inevitable impurities. The method includes steelmaking, continuous casting, hot rolling, reeling, cold rolling, continuous annealing and flattening working procedures. The quick and thinning stamping processing new energy automobile battery shell steel and the method have the advantages that the quick and thinning stamping processing new energy automobile battery shell steel produced by the aid of the method can adapt to quick stamping and thinning stamping processing requirements, and the problem of poor forming properties of low-carbon battery shell steel can be solved by the aid of the quick and thinning stamping processing new energy automobile battery shell steel andthe method; control points of technologies for producing the quick and thinning stamping processing new energy automobile battery shell steel are clear and definite, and the quick and thinning stamping processing new energy automobile battery shell steel and the method are good in implementation and low in production cost.
