Abstract: Provided is a steel sheet having excellent surface roughening resistance and a manufacturing method thereof. The steel sheet for cans contains 0.0040 to 0.01% C and 0.02 to 0.12% Nb. An average ferrite grain size in a cross section in the rolling direction in a region ranging from a surface layer of the steel sheet to a position 1/4 of a sheet thickness away from the surface layer of the steel sheet is set to 7 µm or more and 10 µm or less, and the average ferrite grain size in a cross section in the rolling direction in a region ranging from the position 1/4 of a sheet thickness away from the surface layer of the steel sheet to a sheet thickness center portion of the steel sheet is set to 15 µm or less. The average ferrite grain size in the cross section in the rolling direction in the region ranging from the surface layer of the steel sheet to the position 1/4 of a sheet thickness away from the surface layer of the steel sheet is set smaller than the average ferrite grain size in the cross section in the rolling direction in a region ranging from the position 1/4 of a sheet thickness away from the surface layer of the steel sheet to the sheet thickness center portion of the steel sheet. The steel sheet for cans is obtained by cooling a steel sheet at 50 to 100°C/s within 1 second after final finish rolling, is wound at 500°C to 600°C, is subsequently subjected to pickling treatment, is subjected to cold rolling at a reduction rate of 90% or more, and is subjected to continuous annealing at a temperature of equal to or more than a recrystallization temperature to 800°C or below.

Abstract: A component composition contains, by % by mass, 0.0016 to 0.01% of C, 0.05 to 0.60% of Mn, and 0.020 to 0.080% of Nb so that the C and Nb contents satisfy the expression, 0.4 ‰¤ (Nb/C) × (12/93) ‰¤ 2.5. In addition, the amount of Nb-based precipitates is 20 to 500 ppm by mass, the average grain diameter of the Nb-based precipitates is 10 to 100 nm, and the average crystal grain diameter of ferrite is 6 to 10 µm. Nb is added to ultra-low-carbon steel used as a base, and the amount and grain diameter of the Nb-based precipitates are controlled to optimize the pinning effect. Grain refinement of ferrite is achieved by specifying the Mn amount, thereby achieving softening and excellent resistance to surface roughness of steel. Therefore, it is possible to provide a steel sheet for cans with excellent surface properties which causes little surface roughness and no film exfoliation after drawing and ironing, and also provide a method for producing the steel sheet.
