S-N curve for P265GH?

[Mertsi1340]

Hi,
I am looking for the S-N curve of P265GH (EN 10 028-2) pressure vessel steel. The designation for this material in
- DIN is HII
- ASTM/ASME is A 516 GR 60.
I need the curves in order to carry out a pressure vessel fatigue analysis where the mentioned material is used.

Alternatively, I will be exteremly grateful if some one could provide me with the following information about this material :

1- Strength coefficient (sigma f)
2- strength exponent (b)
3- Ductility coefficient (epsilon f)
4- Ductility exponent (c)

Once again thank you for you help!

In lieu of the approach your taking to obtain this information, if you have access to the ASME Boiler and Pressure Vessel Code, review Mandatory Appendix 5 in Division 2 of Section VIII. This Appendix (Article 5-1) contains fatigue curves for various pressure vessel steels that would be of benefit to you.
