[QUOTE="Pdvdh, post: 1388586, member: 4191"] Barrels are heated to 1000 - 1100F intentionally, in order to stress relieve the steel after button rifling. Barrel blank steel is also carefully heated prior to shipment to the barrel manufacturers, for a positive purpose. Heating to high temps is beneficial. Even mandatory to produce a safe, useful barrel. Again, an example of high heat being necessary in order to produce a quality result. Heat applied improperly (cutting torch), could no doubt damage a barrel. We're back to finding and using companies that know how to do it right, employ sufficient QA/QC to ensure they do it right, and work at doing it correctly. And then there's the matter of who's responsible to ensure the barrel is suitable for nitride treatment (isn't fire cracked in the throat), is properly cleaned prior to treatment, and is properly cleaned after treatment. If this is too complicated, then maybe avoid the process on your personal barrels. Is it really worth it? That's where this thread is leaning. It all depends... primarily on the opinion of the guy that owns the barrel and has to pay for the treatment process. [/QUOTE]
