ASTM A500 s-n curve??

ASTM A500 s-n curve??

(OP)
Does anyone know where I can get the fatigue curve for astm a500 tubing material?
Also, I am designing a part out of this material and was wondering in order to find the FOS for the design is it correct to divide the maximum stress occuring in the part from FEA by the fatigue strength associated with the number of cycles used?

Fatigue design is not an easy subject because the key is understanding how to determine and apply service stresses. The web site below is probably one of the best and will introduce you to fatigue design;
