nitriding procedure 1

[rudragoo]

Hello

I am trying to find a process procedure with depth of nitride and case Rc for nitriding steel (various kinds). I've Googled but haven't found the right kind of procdure. We wish to use this in spec-ing nitriding for our products as well as QA and testing of the received parts.

I have also searched on this site and have found info that does help but I was hoping to find an actual procedure/spec to call out on my drawings and to pass on to my vendors.

thank you for your help.

I have just been told that we are specifically looking a 4140 material to be spec-ed for the nitriding.

Thanks
