Steel For Battery Shell

الوصف

Battery shell steel of Baosteel（BDCK） is especially designed for coined alkaline battery or rechargeable battery, which is applicable to high-speed and deep drawing battery shell with thinning and stretching process, battery shell with perfect appearance quality needed and battery shell Nickel preplated or post-plated.

(1) good stamping formability. Featuring deep-drawing, thin and small earring.
(2) High dimensional accuracy. The thickness tolerance of pitted surface shell steel is±0.*1mm, and the micro-negative tolerance of shiny surface shell steel is between *0.**7mm and *0.**3mm, which can meet customerss demand.
(3) High surface quality. Characteristic of high purity steel can reduce the blowholes defect caused by materials; the inner quality of good materials can reduce the snowflake defect caused by materials; high-level quality control of surface can reduce the risk of pressing.
