Abstract

PURPOSE:To improve the adhesion of blackened scale formed on a high carbon steel sheet by pretreating the steel sheet having a specified Si content to increase the concn. of Si on the surface and by subjecting the steel sheet to heat treatment for forming blackened scale. CONSTITUTION:A cold rolled steel sheet or a polished special steel sheet contg. 0.35-1.00% C and >=0.15% Si is used as starting material. This high carbon steel sheet is treated by electrolytic degreasing in an electrolytic soln. contg. silicic acid, or annealing to increase the concn. of Si in the surface of the steel sheet. The pretreated steel sheet is heat-treated in a special atmosphere to form blackened scale. The adhesion of the blackened scale formed on the high carbon steel sheet and the corrosion and wear resistance of this sheet are improved.
