Abstract (en)
[origin: EP2098312A1] A laminated steel sheet used as a raw material has a tensile strength TS after forming at an equivalent strain seq of 1.6 is 800 MPa or less and satisfies 0.25 ‰¤ tb/to where tb is a sheet thickness at a fracture surface after fracture and to is a sheet thickness before the fracture. In forming the laminated steel sheets, forming is conducted so as to satisfy the relationships below: 1.5 ‰¤ h / R ˆ’ r , 2.8 ‰¤ R / r 1 , a ¢ n ¢ d 1.1 ‰¤ r 2 / r 1 where h: a height from a can bottom to an opening edge portion; r: an outer diameter of a can body; R: a radius of a circular blank before forming having a weight equivalent to a weight of a final formed can body; r 1 : an outer radius of an opening edge portion; and r 2 : an outer radius of a bead portion.
