[QUOTE="Trickymissfit, post: 476443, member: 25383"] Now I'm quite familure with liquid salt, but never put the two together! How does one deal with the 1460 degree temps? As well as warpage? I've not done any liquid salt work since the mid 1970's, and I'm sure some things have changed over the years (you don't see it used very much anymore) There is another form of liquid nitride treatment that actually injects cracked amonia into the furnace (temps escape me). I did my race hemi cranks that way a zillion years ago. Parts come out a sooty black, and the case might be .0075" deep at best. I've aslo done plasma a little bit (very small parts), but not very much. Most of what I did was with gas at 900 degrees. Process was slow, but quality was excellent (usually carborized & hardened 8620 or 4000 series C/H that had been prehardened) Tell us a little more about this process as it's new to me. And is it or is it not a granular penetration? Also how deep of a case are you working for? gary [/QUOTE]
