What type of stainless is common in firearms? I know most barrels are 416r,but what about the frames and other parts. My 1911 has a cast stainless frame and a Caspian "barstock" slide and I have a Cetme with a cast stainless receiver...But I am clueless of what type of stainless they actually are. Does anybody know or are these factory kept secrets?

Usually 400 series 410, 416, ect. 300 series is for chemical resistance buy still could be used. 400 series is tougher than 300 series. Also 400 series is magnetic.

17-4ph stainless is used where high strength is needed such as revolver cylinders. It can be hardened.

Most of the stainless guns or weapons I've bought always advertized that they were made from 440 Stainless Steel. It's a good stainless with great metallurgical properties for strength & durability.

There are three 440 stainless steels. 440A, 440B and 440C. C has the higher level of carbon for hardness. It was invented over 100 years ago for cutlery. If you wish a recomendation for something, I can always quiz the metallurgist at work.

I am just looking into other possibilities of metals to use other than carbon or moly steels or aluminum. I guess I am looking for a stainless that doesn't differ too much from other steels ,as far as welding,machining and heat treatments,but offers more resistance to the elements.

I will ask about welding but I must know which part you are talking about. The required strength for a revolver cylinder is much higher than those necessary for a 1911 frame.

Will be used for frame or receiver mainly ,maybe other small parts or bolt. It will not be used for a cylinder or chamber of any kind
