A high-strength, high-permeability steel sheet for picture tube band comprises, in mass percent, C: 0.003-0.010%, Si: 0.5-1.0%, Mn: 1.0-2.0%, P: 0.04-0.15%, S: not more than 0.02%, Al: not more than 0.030%, N: not more than 0.004% and the balance of Fe and unavoidable impurities, has a chemical composition satisfying C&#xd7;Mn&#xd7;P&#x2267;2.5&#xd7;10, and has a ferrite crystal grain diameter of 10-100 &#x3bc;m and a yield stress of 300 N/mmor higher, and preferably has a specific permeability &#x3bc;0.35 in a DC magnetic field of 0.35 Oe of 400 or higher. The steel sheet can be produced by regulating the hot-rolling coiling temperature to 600-700&#xb0; C. and selecting an appropriate combination of the cold rolling reduction ratio and a final annealing temperature in the range of 750-900&#xb0; C.

A process for producing a coil of a hot rolled austenitic steel strip wherein a hot bar of austenitic stainless steel is hot rolled to a strip by multiple pass rolling with a total rolling reduction and finishing temperature controlled within the hatched area of FIG. 1; and wherein the hot rolled strip is allowed to cool in air for 3 to 10 seconds, cooled with water and then coiled at 400.degree. to 600.degree. C. The product has recrystallization substantially completed and sensitization prevented, and therefore, need not be annealed before it is subjected to a pickling process.
