Re: Question for the metallurgists out there......
I have used Stellite both as a cuttiing tool and i have machined the stuff, by machining i usually mean grinding and EDM.
With brazed tipped diamond tooling, i have also performed light machining operstions turning small 45 degree countersinks, in Stellite Die inserts used in the manufacture of wood screws
It is extremely hard and very brittle, in my experience its best quality is its compressive strength.
I understand that some 1911 barrel manufacturers EDM there pistol barrel rifling, so this technology already exists.
Apart from cost( a 1/4"x 1/4"x 3" toolbit costs me the equivalent of $15)i think you would encounter to many problems to make the manufacture of this barrel viable, due mainly to the materials brittleness.
During my apprenticeship we conducted shear tests on various cutting tool materials and the stellite came out worst apart from carbide.
Clamp the above tool bit in a vice and tap it with a hammer and it will snap with little force, do this to an equivalently sized piece of hardened and tempered high carbon steel and it will flex and spring back into shape.
If you could cut them, your barrel threads would most likely collapse on tightening into your action and i think there could be a very real risk of a chamber explosion with your first hot load!
