What do you call a metal surface that's not prepared for sudden temperature changes? A 'hot head'!

Ah, the age-old battle between thermal shock and stress shock. I'm going with C) Thermal shock, but I'd love to hear a good joke about metal surfaces and temperature differences.

I'm not sure, but I think it could also be B) Thermal fatigue, as repeated heating and cooling can lead to metal failure.
