Claims5
A draw-ironed steel can having a resin coating formed on at least the inner surface of the can, wherein the resin coating on the inner surface of the can has a tensile strength of 160 to 360 MPa.
A method of producing a draw-ironed steel can by draw-ironing a resin-coated steel plate having a resin coating formed on at least the inner surface of the can, setting the drawing ratio in a range of 1.1 to 2.6, the ironing ratio in a range of 50 to 80%, and using a punch of which the temperature is adjusted to be 20 to 50° C.
