I consistently blue my rotors, and that happens at 300 °C / 600 °F. This is a neat reference: "[https://en.wikipedia.org/wiki/Tempering_(metallurgy)](https://en.wikipedia.org/wiki/Tempering_(metallurgy))"
I think 1000 °F would be pretty extreme, but maybe possible with a heavier rider on a long sustained steep descent.
