Summary for deep drawn stainless steel form tools Discussion
Deep drawn stainless steel form tools are the focus of this thread, with Jamie VanBeek asking what coating is best for a severe draw after having problems with TiN and getting vague sales answers. He notes that many articles recommend CVD TiC and other coatings for severe draw conditions, but he wants an experienced, non-sales opinion before spending money on more trials. Years later, Jonathan Weaver adds that he is looking for a solution for existing tooling and would prefer not to use CVD, suggesting plasma nitriding plus a PVD coating as a possible route. No one in the excerpt provides a definitive tested recommendation, so the discussion remains open and cautious rather than conclusive.
Q. Reading a handful of articles a lot of authors are saying to use CVD Tic and Most coatings for severe draw conditions. I am doing a severe draw and having issues with the Tin coating and everyone that I have talked to (salesmen) cannot give me a straight answer on what to use. If anyone, with the exception of someone trying to sell me something, give me an experienced answer on what is the best coating to use in this situation. With the cost of coatings I would rather not experiment.
Thanks Jamie VanBeek

Q. Hello, Did you find a solution to your problem? This is a problem I would like to solve for existing tooling – so I don’t want to use CVD. I was hoping that maybe plasma nitriding and a PVD coating would do the job.
