Abstract

Effect of kind of lubricants on press forming ability of galvannealed steel sheets, which is susceptible to powdering, was investigated by cylindrical shell draw test, drawbead test and Bowden's friction test.
The lubricity was found highest in the case of using phosphate coating + soap, followed by press lubricants, solid lubricants, resin and rust preventive oil in this order.
The correlation coefficients between the results obtained by each test were found to be relatively high and the influence of powdering on lubricity was not observed.
