Nitriding is not a coating, it will not affect the dimensions of the bore. The bore will be exactly as it was before nitriding, just harder and more lubricious. Nitriding changes the metals surface at the molecular level.

I am impressed that John said he didn’t notice any accuracy loss from the nitriding of his barrel. I would imagine that he simply coated the outside of the barrel. It is hard for me to imagine that the inside would allow for any coating. He also said that it made it easier to clean. I’m sure this is desirable for any sportsman.

Nitriding is not a coating. Its a treatment. It penetrates the steel, making it harder; doesn’t plate over it.

I am interested. But I need some answers to these questions:
1. Nitriding process can be used for non-stainless steels too or only for stainless steels ?
2. Can be treated the actions, bolts, breech of shotguns and shotgun barrels ?
3. what are the prices for a pair of action-barrel /

We are talking about completely different materials and grain structures of a crankshaft compared to 416SS and also the case depth of the nitrided layer of the crankshaft is not comparable to that of processed 416 SS or 4140 barrel.

Interesting and puzzling. I have a nitrided crankshaft in my ’68 Plymouth Barracuda. What puzzles me is that the crankshaft grew very slightly during the nitriding process. I have no idea of the process used however. The crankshaft grew approximately 0.010″.

To my knowledge this is not the same process used by Black Star. After processing it will not be feasible to re-machine since it will be case hardened.

In Europe they have been Salt Bath Nitriding firearms conponents since the early 1900s.

If you need additonal information feel free contact me by e-mail or cell to discuss.

Is this the same process used to make the “Black Star” barrels of the past?
Is it possible to re-chamber or re-machine the barrel after this process?

Ernie Stallman at Badger Barrels has been a proponent of barrel nitriding for over twenty years. Maybe Ernie was just ahead of the curve.
