Seamless can with necked-in portion |
摘要 |
An organic resin-coated seamless can with necked-in portion is disclosed, which is produced by subjecting a resin-coated steel sheet to drawing-re-drawing for reducing thickness or to drawing-re-drawing-ironing for reducing thickness-ironing and which has a ratio of diameter of necked-in portion to diameter of body of 0.9 or less than that, said steel sheet being coated by 5- to 30- mu m thick organic resin layer on both surfaces of aluminum-killed, surface-treated steel sheet of 0.01 to 0.13 % by weight in total carbon amount and not more than 6.5 mu m in average grain diameter having been subjected to over-aging after continuous annealing to adjust to not more than 10 ppm in solid-dissolved carbon amount. This can scarcely has rough surface or pinholes in the necked-in portion even when the necked-in portion has been considerably compressed upon its formation.
