Abstract

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.
