nitriding

Dear friends
I have been reading about nitriding and it's applications for surface hardening of H13 steels. I found that it can be done in salt bath furnace,gas furnace or plasma which the last one is very expensive. I want to use nitriding for surface hardening of hot forging dies and I want to know which problems may be occur in future if I use salt bath furnace (except pollution).
Thanks Mahdi

Another option is fluidized bed nitriding. It acts like salt bath nitriding and is by far safer and practically nonpolluting. Zbigniew Rogalski

In your position I would call my local heat treatment company, they generally have a metalurgist on the staff & heaps of practical/economical solutions, backed by years of practical experience. You could compare the advice from several such sources & maybe do some trials.
