A process for producing a strip of steel sheet, for the production of metal packaging, comprising forming a hot-rolled strip of steel having the following composition by weight: carbon up to 0.08%, silicon </=0.020%, manganese between 0.05% and 0.60%, sulphur </=0.020%, phosphorus </=0.020%, nitrogen up to 0.016%, aluminum up to 0.060%, copper </=0.06%, nickel </=0.040%, and, optionally, chromium and boron, the balance consisting of iron and inevitable impurities, then carrying out a first cold-rolling operation on the hot-rolled strip in order to obtain a blank, subjecting the blank to a continuous recrystallization annealing operation, carrying out a second cold-rolling operation on the blank in at least two passes in order to obtain the sheet with its final thickness, wherein between the two passes of the second cold rolling, the strip of sheet is subjected to an ageing operation at a temperature of at most 300 DEG C. for a time which can range from a few minutes to several days.
