R&D Update: Lubrication and galling in stamping of galvanized AHSS - Part III

April 15, 2008

By:

Forming of galvanized AHSS involves higher contact pressures at the tool-workpiece interface compared to forming mild steel. Under these severe interface conditions, improper selection of lubricants, tool materials and tool coatings may result in high scrap rates and galling in stamping production.. Based on SDT results, polymer-based lubricant with EP additives and water-soluble DFL were found to be most effective, Synthetic lubricants showed also reasonably small frictional responses with a PVD coated die in forming GA coated strips.
