Title:
STEEL SHEET FOR TENSION MASK, METHOD FOR PRODUCING THE SAME AND TENSION MASK
Document Type and Number:
WIPO Patent Application WO/2001/046480
Kind Code:
A1
Abstract:
A method for producing a steel sheet for a tension mask which comprises the steps of hot rolling a steel having the chemical composition in wt.%: C: less than 0.1 %, Si: 0.05 % or less, Mn: 0.4 to 2 %, P: 0.03 % or less, S: 0.03 % or less, sol.Al: 0.01 % or less, N: 0.01 % or more, balance: substantially Fe, cold rolling the hot rolled steel sheet followed by annealing, and subjecting the resulting steel sheet to a secondary cold rolling at a reduction in thickness of 35 % or more. A steel sheet produced by the use of the above method exhibits excellent resistance to creep in blackening processing and also has an excellent magnetic shielding property such that it exhibits a non-hysteresis magnetic permeability of 3400 or more at a DC bias magnetic field of 0.35 Oe, and thus causes no color divergence when used for a tension mask.
