The surface of the steel plate is coated with Fe-Cr alloy composed of (in wt.%) 4.5-5.5 % C, 20-25 % Cr, up to 0.2 % Mn, 0.5-1.5 % Si, 3.0-7.0 % Mo, 0.4-1.5 % V, 0.5-2.5 % W, 3.0-7.0 % Nb and balance Fe. The Fe-Cu alloy melts in a high frequency vacuum furnace, is heated to 900 deg.C under inactive gas atmosphere, and is sprayed on the surface of the steel plate through a nozzle of the furnace. The coated steel plate has the improved abrasion, heat and melt-fusion resistances.
