In the manufacture of steel strip or sheet, suitable for use as deep-drawing steel for the manufacture of can bodies by deep-drawing and ironing, there a re performed the steps of (i) providing a low-carbon steel in the form of a sla b, (ii) rolling the slab in the austenitic region to reduce its thickness to a transfer thickness, (iii) cooling the rolled slab having the transfer thickness into the ferritic region, (iv) rolling the rolled slab in the ferritic region to a finished thickness. To provide a steel having reduced tendency to "earing" in can body manufacture, the transfer thickness is less than 1.8 mm and the total thickness reduction in the ferritic region from th e transfer thickness to the finished thickness is less than 90 %. |
