I have some questions on 4140 and 4340 regarding the suitability for use as material for a pistol slide/frame
1. How hard should the metal be to prevent peening of the breach face, locking lugs,firing pin retainer area,slide stop catch and muzzle lockup?
2. Will Melonite processing reach a temperature that would stress relieve the slide and frame?
3. Current idea is to rough machine the parts in an annealed state leaving enough material to do the final machining to avoid the inevitable movement/warp of the steel after quenching and tempering to desired final hardness.
4. Is 25-30rc hard enough for the frame and 35-40 for the slide? Looking to achieve durability and not become brittle, with the Melonite or DLC coating to handle the surface hardening for wear prevention.
We are looking at 416 and 17-4 as well for slide and frame for the stainless version.
