Good afternoon,
For those of you that might be machinists or work with metal welders possibly blacksmiths. I have a question, being a mechanic and having been to college and taught to weld and braze. If you heat metal to the point of de-brazing but it never changes colour and let it cool naturally do you change it's hardness? The exact example my shotgun barrel had a cantilever mount on it. Key word had I removed it by heating the mount with an oxy acetylene torch so that the mount was a very dull red once that was obtained the mount came off with very little pressure. The barrel it's self got hot to the touch but never changed colour and most likely f the braze stayed on the barrel. I figure that it's hardness didn't get changed but wanted another opinion.
