I have had 10’s of thousands of parts liquid nitrided (ferro nitro carburizing), gas nitrided, and carburized.

We are just now doing testing of Gas FNC Which is similar to gas nitriding but different.

If I was you, I would look for a place in town that does liquid nitriding and see if they can toss your parts in with a batch. Make sure they keep the temps below 1100F and you should be fine. Have them apply the black oxide coating and your parts will look amazing.

You can’t get good results in all metals with the other processes and anything with thin features will become brittle with gas nitriding.
