STEEL SHEET USED TO MANUFACTURE A CONTAINER AND METHOD OF MANUFACTURING THE SAME

摘要

A steel sheet used to manufacture a container, wherein the steel sheet includes a chromate film layer or a film layer including Zr on the Ni plating layer, the Ni plating layer includes one or more of a hydroxyl Ni and a Ni oxide, an adhesion amount of the Ni plating layer in terms of an amount of Ni is 0.3 g/m2 or more, a concentration of oxygen atoms of the Ni plating layer due to the hydroxyl Ni and the Ni oxide is 1 to 10 atomic %, an adhesion amount of the chromate film layer in terms of the amount of Cr is 1 to 40 g/m2, and an adhesion amount of the film layer including Zr in terms of an amount of Zr is 1 to 40 g/m2 or more.
