Steel sheet with low aluminum content for containers

A process for manufacturing a steel strip with low aluminum content, comprising:

• hot-rolling a steel strip comprising between 0.050 and 0.080% by weight of carbon, between 0.25 and 0.40% by weight of manganese, less than 0.020% by weight of aluminum, and between 0.010 and 0.014% by weight of nitrogen, the remainder being iron and inevitable trace impurities, to form a strip;
• subjecting said strip to a first cold-rolling, to produce a cold-rolled strip;
• annealing said cold-rolled strip, to form an annealed cold-rolled strip;
• and
• subjecting said annealed cold-rolled strip to a secondary cold-rolling,
• wherein said annealing is a continuous annealing comprising:
• raising the temperature of the strip to a temperature higher than the temperature of onset of pearlitic transformation Ac1,
• holding the strip above this temperature for a duration of longer than 10 seconds,
• rapidly cooling the strip to a temperature below 100° C. at a cooling rate in excess of 100° C. per second,
• then performing a plastic deformation operation comprising an elongation of the strip with a percentage elongation ranging between 1 and 5%,
• then thermally treating the strip at a low temperature ranging between 100° C. and 300° C. for a duration in excess of 10 seconds, and
• cooling the strip to room temperature.
