Abstract

A major obstacle for introducing high volume forming of stainless steel sheet is the tendency of lubricant film breakdown resulting in pick-up of workpiece material on the tool surface and subsequent scoring of the workpiece surface (galling). Conventional technology to delay galling is the use of a suitable lubricant to reduce friction. For severe deep drawing operations lubricants with extreme-pressure additives such as chlorinated paraffin forming oils are often used. Therefore, conventional production techniques should be optimized for the use of stainless steel aiming at improved quality enhanced cost effectiveness and improved environmental aspects. Long-term model wear tests showed that the TNO slider-on-sheet method is well designed to assess galling phenomenon. Optimal combinations were found, based on a thorough investigation of the performance characteristics of advanced tool material- lubricant combinations for specific stainless steel qualities used in or intended for automotive and domestic applications.
