Foxtrot. from the engineering specs I have read the treatment has better wear and corrosion resistance even than Stainless. I have also read that stainless doesnt accept the treatment as well as regular chome-moly or just plain steel. And that is the reason you dont find melonite or tenifer treated Stainless Steel. You did nail the difference between tenifer and melonite. The salt used in the melonite process is not as hazardous to work around or to dispose of. But the outer layer of the stainless base material is not near as accepting the process.
