I am trying to find an S-N curve for cold worked stainless steel. Any suggestions on where to look?
 
You'll need to be more specific before even starting. Fatigue varies widely for different alloy and heat treats. "Stainless steel" is not a sufficient description to get any meaningful information.

First get more specific composition information. Even then, I don't have a good answer for publicly available SN curves. My best recommendation is to either engage somebody with that information, or research in an engineering university library.

All I have is a mil spec. that does not provide tensile strenght for 316 Stainless Forging cold-worked. The material is under Mil-S-7702 Class C. If you have any reference material for Tensile strenght then I could put together a Goodman Diagram.
