316L Fatigue Curves 1

[22west]

Anyone know where I can get fatigue curves for 316L at various temperatures?

ASME Boiler and Pressure Vessel Code, Section VIII, Div 2, Appendix 5.

Thanks!

I should have noted, considering your mentioning various temperatures, only an ambient temperature fatigue curve is provided. The effect of temperature is considered in the elastic modulus adjustment (if your analysis uses other than an ambient temperature elastic modulus to calculate stress, you mulitply the calculated stress by the ratio of room temperature elastic modulus to that used in the analysis). Essentially, strain range versus cycles to failure is relatively independent of temperature for the temperature ranges permitted in the Div 2 curves, below the creep regime.
