Nitriding screw threads

[metalonis]

Is there an ASM (or other) specification for a suitable process for nitriding screw threads in annealed austenitic stainless steel?

I do not know of any consensus standards, but here are two processes used in industry for threaded parts:

Thanks CoryPad. BTW, I meant AMS, not ASM.

You can try SAE AMS2759/6B Gas Nitriding and Heat Treatment of Low-Alloy Steel Parts and SAE AMS2759/10A Automated Gaseous Nitriding Controlled by Nitriding Potential.
