I just read on a bottle of "Bjorg" sunflower oil:

"[The oil] is cold-pressed (T<60°)"

Notes:
* 60 deg C = 140 deg F
* I don't know about other types or brands of oils
* I suspect that at these temperatures, there is very little
denaturation, and that proper storage conditions are more important
than the temperature reached during extraction.
