The steel can be coated with differing thicknesses of tin, and even different thicknesses on the two faces (differential coatings) may be produced to cater for varying conditions at the internal and external surfaces of a container.
High-strength steel of just 1.2 mm thickness protects the battery even if there is little deformation space in the event of a collision with foreign bodies from below.
Read more about electrolytically coated tinplate. Deviations in coating weights are possible in the range of 1.00 to 11.20 g/m² (0.100 bis 1.000 lb/bb).
NOTE: Battery heights can vary due to individual requirements and material specifications. Consult factory for exact tray dimensions and specifications. HEIGHT DIMENSION SPECIFICATIONS
Dimensional tolerances 1. Thickness The thickness tolerance is –4% + 5% measured with a calibrated micrometer (0.01mm accuracy) at least 10mm from the trimmed edge. 2. Feather edge The difference in thickness, between the centre of a sheet and a position 10mm from the trimmed sheet edge, will not exceed 8% of the sheet centre thickness. 3. Width
steel sheets to prismatic-type battery cases has been studied (Fig. 2). There are two Ni coating methods for battery cases: post-coating in which formed cases are coated using a barrel or other similar tool and pre-coating in which coated sheets are formed into cases. For post-coating, a thick coating layer can be formed on the outer sur-
