More Information
Summary:Provided is a steel sheet for cans with high strength and sufficiently high formability particularly as a material for a can body with a neck portion. The steel sheet for cans of the present disclosure has a chemical composition containing, in mass%, C: 0.010 % to 0.130 %, Si: 0.04 % or less, Mn: 0.10 % to 1.00 %, P: 0.007 % to 0.100 %, S: 0.0005 % to 0.0090 %, Al: 0.001 % to 0.100 %, N: 0.0050 % or less, Ti: 0.0050 % to 0.1000 %, B: 0.0005 % to less than 0.0020 %, and Cr: 0.08 % or less, where 0.005 ? (Ti*/48)/(C/12) ? 0.700 is satisfied; and a microstructure with a proportion of non-recrystallized ferrite of 3 % or less, wherein an upper yield stress is 550 MPa to 620 MPa.
