본 발명은 단축 변형의 최대 주왜곡의 최대값이 0.25 이상 또한 평면 왜곡 변형의 최대 주왜곡의 최대값이 0.1 이상인 것을 특징으로 하는 전지 용기용 강박이다. 본 발명에 의하면, 전지 용기용으로서의 엄격한 성형 가공을 행하는 경우에 기재의 깨짐을 억제 가능한 전지 용기용 강박을 제공할 수 있다. The present invention provides steel foil for battery containers, the steel foil being characterized in that the maximum value of the maximum principal strain in uniaxial deformation is not less than 0.25 and the maximum value of the maximum principal strain in planar strain deformation is not less than 0.1. The present invention is able to provide steel foil for battery containers that is capable of restraining cracking of a base material when subjected to a severe forming process for battery containers.
