摘要:
Alloyed-zinc-plated steel sheet the alloyed layer of which is minutely cellulated is disclosed. Such an alloyed-zinc-plated steel sheet can be prepared by carrying out the vacuum deposition plating in an inert atmosphere containing 1.0-30 ppm oxygen by volume oxygen and subjecting the plated steel sheet to an alloying heat treatment.
