By using the hot-rolled, cold-rolled and continuous annealing at above temperature, soft tin-plated disc of T2 or less, excellent workability is secured and baking after D & I (D & I, Drawn and Ironned) processing in the manufacturing process. The present invention relates to a method of improving the stability of a can by hardening a material in a processing process to increase the pressure resistance of the can, and also has excellent processability even by low temperature annealing, and also has excellent pressure resistance to the contents of the can. It can be used as a material steel plate for severely processed two-piece containers.

Add 0.20%, aluminum 0.03 ~ 0.06%, zirconium 0.005 ~ 0.025%, but adjust the amount of zirconium more than (91/14) N and less than (91/14) N + (91/32) S. After finishing homogenizing aluminum-killed steel containing inevitably contained elements at 1200 ~ 125 ℃, finish hot rolling temperature is 900 ~ 930 ℃, just above A r3 transformation point, and hot rolling is performed at 620 ~ 700 ℃. After cold rolling to 85 ~ 90%, it is continuously annealed at low temperature annealing temperature range of 650 ~ 720 ℃.
