Document Type and Number:
WIPO Patent Application WO/2000/073518
Kind Code:
A1
Abstract:
A method for producing a steel sheet for a shadow mask which is excellent in the accuracy with respect to thickness in longitudinal direction, characterized in that a steel comprising, in mass %, 0.1 % or less of C, 0.05 % or less of Si, 0.1 to 0.5 % of Mn, 0.03 % or less of P, 0.001 to 0.05 % of S, 0.002 to 0.15 % of Sol.Al, and 0.008 % or less of N, the residue of the steel consisting substantially of Fe, is hot rolled, the hot rolled sheet is subjected to a decarburization annealing, and then the resultant steel sheet is cold rolled to a desired thickness.
