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.
It may also depend on the environment in which you are running. (i.e. Temperature)
The reliability mostly depends on how hot it gets over a period of time. Sizing up might be beneficial
