This paper dealt With the corrosion properties of hot-dip aluminized steel and 304 type stainless steel in various corrosion environments. Pitting and crevice corrosion rates of hot-dip aluminized steel were larger than those of 304 type stainless steel. but corrosion mode of the former was general corrosion and its mode of the latter was localized corrosion. By immersion test in 3.5% NaCI solution. also. corrosion rate of hot-dip aluminized steel was faster than that of 304 type staln1ess steel. In anodic polarization test. corrosion potential of 304 stainless steel was noble than that of hot-dip aluminized steel and showed better passivation behavior.
