Being the steel sheet which possesses the electromagnetic shielding effect which the shield can do the electromagnetic field which the steel sheet

摘要

It is superior in the point of high electromagnetic shielding ability, the steel sheet and the hot dipping steel sheet are disclosed. The aforementioned steel sheet, weight % of total 0.150 C of the quantity which is below, N and S and 0.1 - 1.0 weight % Mn of the quantity and, 0.5 weight % Si of the quantity below and, 1.0 weight % Al of the quantity below and, 0.06 weight % is produced from P of the quantity below, and the constitution which includes with remainder Fe and the element which exists inevitably shows the yield strength above 18kg/mm2, and the extension of 40% or more. The aforementioned hot dipping steel sheet, weight % of total 0.0150 C of the quantity which is below, N and S and 0.2 - 0.8 weight % Mn of the quantity and, 0.6 weight % Al of the quantity below and, 0.4 weight % Si of the quantity below and, 0.06 weight % P of the quantity below, being conditional, and the total of Mn, Al, Si, and P becomes 0.2 - 1.0 weight %, remainder Fe and, is produced from the constitution which includes the element which exists inevitably. Is a tolerance for tunic of the corrosion-resistant element of the surface vis-a-vis corrosion the hot dipping steel sheet in addition to possessing high yield strength.
