The target year of corrosion for new developing vehicles is aimed to 1-2-5-10 year (underbody/underhood/exterior-interior-secondary surface cosmetic corrosion and functional corrosion). The car makers have developed cyclic laboratory test for evaluating the corrosion resistance of steel components and subsystems. Perforation life estimation used corrosion model method. In this paper, the comparisons for door hemming flanges of PG and Lab corrosion test will be discussed.
