Fatigue analysis for C95800 in ASME BPVC Sec VIII div.2

[victor6397]

Hello!
I have to perform a fatigue analysis of an element of material C98500 (Nickel-aluminium bronze or copper alloy), but none of the curves in annex 3-F fits well. Maybe the one in c) for 70-30 coppe-nickel?

Can someone help me or give me some ideas on how to do it? I can use other codes as well.

Thank you!

That material is not covered by the existing fatigue curves in VIII-2.
