In recent years, manufacturing engineering for no lubricant metal forming process has been desired from the uneasiness for the global environmental safeguard. From this viewpoint, the lubricant pre-coated steel sheet consisted of resin layer with wax particles has been developed. This research was carried out to investigate the friction behavior of the lubricant pre-coated steel sheet by the method of Bowden-Leben friction testing. The friction behavior was investigated under the conditions that normal load, sliding velocity, temperature and spherical radius of the pin were changed broadly.
