The objective of this article is to study the tribological properties that affect the deep drawing of SUS304 BA stainless steel. The tooling material is hardened SKD11 cold work tool steel. A tribometer was used to study the tribological properties between the contacting surfaces of the tooling material and the workpiece material. The study results were linked to the results of the deep drawing experiment. The study shows that lubricant can reduce the friction coefficient between the contacting surfaces of the hardened SKD11 tool material and SUS304 BA stainless steel by more than 6 times. The hardness of solid film can reduce the wear volume of tooling materials. However, the TiAlN-coated tool cannot deep draw SUS304 BA stainless steel while the hardened SKD11 tool can deep draw successfully at 131 cups for SUS304 BA stainless steel under dry conditions. DLC film helps improve the tribological properties between the contacting surfaces of the hardened SKD11 tool steel and SUS304 BA stainless steel and can also be used for deep drawing more than 1500 cups under dry conditions.
