Abstract (en)

An alloyed hot-dip galvanized steel sheet is obtained by forming a hot-dip galvanized layer on the surface of the steel sheet and then alloying the steel sheet. The steel sheet exhibits a potential of -850 mV or less when it is immersed in a zinc sulfate-sodium chloride electrolyte. Alternatively, when it is electrolyzed according to constant potential electrolysis process in a zinc sulfate-sodium chloride electrolyte at a potential in a range from -940 mV to -920 mV, the quantity of electricity consumed is less than or equal to 0.5 C/cm<2>. The steel sheet exhibits excellent processability and particularly excellent sliding property. <IMAGE>
