DRAWN AND IRONED CANS WITH THIN NICKEL COATING AND METHOD OF FORMING THE CANS ABSTRACT OF THE DISCLOSURE Seamless cans are drawn and ironed from steel sheet having a very thin coating of nickel on both sides. The steel may be flat rolled blackplate and the nickel may be plated onto the steel by drawing a continuous strip or sheet of the steel through a conventional electroplating bath to deposit the very thin nickel coating. The coated steel is cut into blanks which are drawn into cups, and the side wall of the cups are then ironed in the conventional manner to produce the desired thickness and height for the finished cans. The nickel coated steel may be chemically treated to increase storage life of the material before drawing and ironing. The drawn and ironed cans may also be chemically treated to enhance the adhesion of lacquer applied to the cans.
