Can anyone help me with a good tool steel for stamping 304 stainless steel. we are currently using D-2. I was told CPM10-V would be a good choice.
The problem we are having is constant dulling of punch and die. we get anywhere from 1,200 to 3,500 hits and then need to sharpen. Coating the tools hasn't seemed to help either.
We are stamping .016 304 stainless steel. Any help with a tool steel and cutting clearance would be greatly appreciated.
