PROCESS FOR ELABORATING A MATERIAL FOR MANUFACTURING METAL PACKAGES, PARTICULARLY FOODCANS, CONSTITUTED BY A PROTECTED STEEL SHEET |
摘要 |
The invention relates to mild steel sheet, having deposited on at least one of its major faces a sub-layer of tin in an amount of 0.1 to 1.05 g/l and a composite coating containing chronmium and chronmium oxide. The content of chromium in the composite coating is more than 5 mu g/cm2 while the content of chromium oxide in the coating, expressed in terms of chromium, is less than 2.5 mu g/cm2. The resultant sheets give improved welds when joined by electric welding and are particularly suited for making can bodies for food cans. |
