Is there anyone here that works in a lab or company(one that does not Nitride parts) that can check the hardness of material?
I already know the answer but it' more like I need it verified by someone not connected to any company that Nitrides parts but is involved in the firearm community and interested in the truth.
I can send a few Nitride treated barrel extensions. I do not think I have any Nitride treated bolts but I'll check.
My suspicion is Nitride treatment of parts that have already been hardened to 60C by carburizing anneals the parts to the point that the lugs of barrel extensions and bolts compress under the impact and headspace increases as a result.
I have already talked to a couple of companies that nitride parts and of course they say Nitride treatment does not soften the parts and also does not change the torque of barrel extensions installed on barrels. I've been installing barrel extensions and re-torquing barrel extensions for 12 years.
I've also read on forums over the years that Nitride treament causes the parts to become brittle due to hydrogen infusion. from the testing I have done that is not true. The parts are softer not more brittle.
