摘要
PROBLEM TO BE SOLVED: To provide a material suitable for an extension-type color selecting device such as a shadow mask and an aperture grill using a tension method, superior in creep resistance characteristic, and to provide a manufacturing method therefor.;SOLUTION: The material for an expansion-type color selecting device of a color cathode-ray tube, includes by mass %, 0.1-1.0% Mo, 0 to less than 0.01% W, 0 to less than 0.2% Cr, less than 0.05% C, the balance substantially Fe, and in that the half-width of a diffraction peak in (211) face is 0.2 or more when measured by X-ray diffraction using Co-K α1 line. The method for manufacturing the material for an expansion-type color selecting device of a color cathode-ray tube, which performs each at least once cold rolling and annealing of the material, comprises employing the material having the above chemical composition, final cold rolling it at a reduction ratio of 30% or more, and then annealing it under a condition which does not cause recrystalization.;COPYRIGHT: (C)2003,JPO
