... slack quench was diagnosed due to a higher bainite-to-martensite ratio, the quench tanks were put on a more regular maintenance schedule. When excessive decarburization was diagnosed, analyses of the raw material, the as-forged material, and the heat treated material were performed to determine where...

... during BLEVEs. The microstructural study showed that the tank steel was NOT austenitized prior to the BLEVE, nor was any evidence found of less ductile transformation products formed due to propane quenching of fire-induced austenite. Unstable crack growth may have begun when two stress-rupture...

... for retempering the tool to its desired hardness can be selected. If low-temperature tempering furnaces are not available, a shop may use a simple holding furnace (for example, a tank heated by boiling water or steam). Quenching from too high a temperature is the second most frequent origin of cracking. Heat...
