Abstract：

Lubricant treated steel sheets forms a solid lubricating film on the surface of the alloyed molten galvanized steel sheets (GA steel sheets) by means of curing, and attaches tightly to the steel sheet surface so as to reduce the surface friction coefficient and improve the lubricant performance. Therefore, the formability of steel sheets is improved, and the cost of raw materials is reduced for purpose. The tests of sliding performance, drawing properties and bulging performance comparing lubricant treated steel sheets with normal GA steel sheets were carried out by appropriate methods, and the forming margin was regarded as evaluation parameters on formability. Then, the actual forming margin tests of automobile panel were conducted. The results show that performances of lubricant treated steel sheets are enhanced greatly in various fields and the forming stability is improved over 60% comparing with normal GA steel sheets. At present, it has been widely used in TOYOTA, HONDA and other automotive plants.
