... Overheating, in the broad sense, consists of exposing a metal to excessively high temperatures for short periods of time. “Excessive” is a relative word. For some alloys, exceeding 1200 °F (649 °C) can be considered excessive temperature. Allowable metal temperatures for wrought superalloys in structural...
