ABSTRACT:
There is disclosed a process for preparing alloyed-zinc-plated steel sheet having excellent deep drawability, which comprises adjusting the temperature of substrate steel sheet of titanium-killed steel essentially consisting of C.ltoreq.0.01%, Si<0.15%, Mn: 0.15-0.85%, Ti: 0.05-0.30%, P.ltoreq.0.02%, S.ltoreq.0.02%, Al.ltoreq.0.05% and balance of Fe, to a temperature within a temperature range T(.degree.C.) defined as 180.ltoreq.T.ltoreq.-240.times.W+292, wherein W(%) is the Ti content of the substrate steel sheet, subjecting said steel sheet to Zn-plating by vacuum vapor deposition, and thereafter maintaining the plated steel sheet for alloying the plating zinc layer and the substate steel at 220.degree..about.320.degree. C. for 1-50 hours in accordance with Ti content of the substrate steel. This process provided alloyed zinc-plated steel sheets having excellent drawability and powdering resistance.
