A. Yo, Mark & Mike!

Malcomizing is a trade name of Lindberg Heat Treating company, now a part of the Bodycote empire. Malcomizing is their old name for their process of nitriding stainless steel, which they now call "Lintride SS". Contact any of their plants, and they should tell you all about it. Realize that since it is a trade named process, "Malcomizing" does what they say it will do; no more, no less.

A. A Yahoo search on malcomizing yielded a number of sites. The number one site said: "This is a proprietary method of gas nitriding for some stainless steels and ductile iron." There were others, including vendors.
