PURPOSE:To provide a high silicon steel sheet excellent in magnetic properties and mechanical properties and its production by means of Si cementation method. CONSTITUTION:The steel sheet is a high silicon steel sheet which contains, by weight, =0.01% C, 4-7% Si, 0.001-0.01% N, and =0.01% Al and in which the amount of the nitrides of Si and Al is regulated to =5ppm. This steel sheet can be produced by applying hot rolling and cold rolling to a slab of low carbon steel with =4% Si content, subjecting the resulting steel sheet to siliconizing treatment-diffusion heat treatment, and then performing cooling at a cooling rate of =25 deg.C/sec through the region from 950 to 900 deg.C and at a cooling rate of =(T-800)/4( deg.C/sec) with respect to sheet temp. T( deg.C) through the region between 900 and 800 deg.C.
