Some passenger vehicles, which were manufactured in 1989 and 1991 and used around Detroit area for 5 years, were submitted for a corrosion investigation. Panels forming the body shell have been classified into five categories with respect to the corrosion environment and were evaluated in terms of their cosmetic corrosion and perforation corrosion behavior. It is confirmed that exterior panels made of two-side zinc coated steel sheet have excellent performance in cosmetic corrosion. It is shown that the corrosion depth at lapped parts under low humid condition decreases with increase in zinc coating weight. With pre-coated panels with zinc coating of more than 45g/m2 the degree of corrosion was slight. It was found that the usage of zinc coating steel sheet improves the anti-corrosion performance of vehicles. (engl. translation from Kawasaki Steel Giho 32 (2000), Number 1, P. 26-31 (jap.)) (VDEh)
