More Information
Summary:A low-carbon rolled steel sheet for a mask for use in a tension type cathode ray tube with bridges, has a composition %: C:0.001 to 0.015%, Si:0.020% or less, Mn:0.2 to 1.8 %, P: 0.02% or less, S:0.010% or less, N: more than 0.010% and not more than 0.025%, Al:0.02% or less, 0:0.010% or less and balance: Fe and inevitable impurities, with the proviso that (N mass %-0.52 Al: mass%) is 0.005 % or more. The provided composition can prevent the lowering of shielding capacity due to terrestrial magnetism.
