Fatigue curve for high strength material per Div.2

[jtseng123]

Dear all,

We have a high strength vessel, UTS is between 86 ksi-93 ksi in cyclic service. But Div 2, Fig 3-F does not have a curve for such UTS. Where can I find one ?

Per 3-F.1.2(a)

... The fatigue curve values may be interpolated for intermediate values of the ultimate tensile strength.

TGS4, thanks
