Steel sheet for containers, and manufacturing method therefor

Providing a steel sheet and a manufacturing method of manufacturing a steel sheet for containers. For example, a steel sheet (or at least a portion thereof) may comprise from about percentage by mass C: 0.0800% or less, N: 0.600% or less, Si: 2.0% or less, Mn: 2.0% or less, P: 0.10% or less, S: 0.05% or less, Al: 2.0% or less, and the remainder Fe. Plate (or portions thereof) can be cold-rolled, and then may be adjusted recrystallization annealing atmosphere, temperature, time or subsequent heat treatment to control the change in N content in steel, for example controlling the N content and the hardness of the surface layer and the thickness of the intermediate layer so that they are within an appropriate range. The surface roughness Ra of 0.90μm or less may be, and the uneven number of peaks per inch length PPI may be 250 or more.
