摘要:
A steel sheet for a heat shrink band having a non-hysterisis magnetic permeability in a magnetic field of 0.35 Oe of 15000 or more and a yield stress of 24 kgf/mm or greater. The steel sheet for a heat shrink band can be produced by a method comprising a step of subjecting a steel containing C in an amount of 0.01 to 0.15 wt % to a hot or cold rolling, a step of annealing the rolled product at 650 to 900 DEG C, and subjecting the annealed product to temper rolling at a draft of 1.5 % or less. The steel sheet for a heat shrink band can be used for producing a cathode-ray tube which is almost free from the occurrence of color slippage and does not suffer the deformation of its panel face.

摘要:
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.
