Annealing case hardened gun parts

This GunTec presentation covers the process of annealing, or softening, casehardened parts so that they can be polished prior to the finishing process. Larry Potterfield, CEO and Founder of MidwayUSA, starts this process by packing each part inside a metal canister, also referred to as a crucible. The parts are covered with charcoal to prevent scaling as they cool. Once the canister is full, it is placed inside the furnace which is heated to 1500 degrees F. The parts are held at that temperature for two hours and then allowed to cool.

Don't you have to re-harden them?

[pickinthatbanjo]

@dougthewelder I would have to agree

[DdeadPsy]

go die stupid f@cking foolish

[dougthewelder]

You don't need to anneal your parts if you use an appropriate polishing compound. You are risking allot of heat warping by annealing and re-hardening these parts after they have been in seasoned use.

1.500 Celsius our Farenhite?

Yes, you would have to re-harden anything that is meant to be hard. Annealing puts metal into its softest state and at 1500 degrees for two hours, the entire piece will be annealed.

this only "softens" the steel enough to be able to polish it because otherwise it's Too hard. you really have to know what you're doing to Anneal properly.
