1045 Cold Drawn Endurance Limit

[Penguineer]

Hello All - I have been searching for the endurance limit of 1045 cold-drawn steel bar but have thus far been unsuccessful. Does anyone know where I can search or have a source I could reference to get this value? Thank you.

I think your best bet will be to use the typical approximation of 1/2 UTS as high cycle fatigue strength. Good Luck otherwise.
