Symptoms: Failures result in a ductile rupture of the tube metal and are normally characterized by the classic fish mouth opening in the tube where the fracture surface is a thin edge. Causes: Short-term overheat failures are most common during boiler start-up. Failures result when the tube metal temperature is extremely elevated from a lack of cooling steam or water flow.

Under rare conditions, and usually in low-pressure boilers, the peak temperature at the moment of failure can be in excess of 1600 o F, a microstructure at the time of failure that is all austenite. When these failures occur, the microstructure does not show the distortion to the austenite, as the transformation to bainite effectively wipes out
