used it, it works ok, problem is it will only harden the outer thou or 2. casehardening is a soak process, so many thou depth per hour of soak…carbon is soaking into the outer layer while the grain structure is altered (high temp) with that thin a case you have no room for grinding.
basically drop the bright red part into the stuff and role it around (i used an old pie plate or the like) and the kasenit sort of fuses to it. you can repeat this a bunch of times before the quench for a thicker case, or so says the package (i was always doubtful as you aren't really giving it a soak - no short cut around that that i know of
i think are right though, the torrington bearings need a hardened shaft. obviously there are advantages to case hardening, but if its just a simple shaft, you could use drill rod, harden and temper it.
tell us more about the application - if it really needs a proper case hardening job (ie 20-40 thou), kasenit won't do and imo its a lot easier to send it to a heat treatment shop than to do a real caseharden yourself (messy, smelly, time consuming).  |
