Investigation was made by using rust protection, lubrication and degreasing evaluation methods to determine the oil film performance on the galvanized steel. The oil type MAL, and T2EB0 developed by CSC provide the superior rust protection and lubricity, which are most compatible with the application to the deep forming of car parts. The oil type 550HN showed superior degreasing properties instead of suppression of the antirust and lubrication performance. The oil type R850Z with the high content of free acid showed the worst performance. The further study on formulation and evaluation technology of preventive and lubricate oil for various forming purpose will improve the surface properties and increase the competition of galvanized steels.
