Quenching: Process and Mediums | Steel | Metallurgy

It is mainly used for quenching highly alloyed cold-work steels, hot-work-steels, high speed steels, air hardening steels, etc. The fluidized bed cooling is slower than water, or oil, and 10% slower than quenching in molten salts, but significantly faster than air. Fluidized bed can operate at any low temperature.

How to realize quenching and cooling with water instead of oil

Compared with quenching oil, the cooling characteristics of water have two big differences: First, the film boiling cycle is too long, making it difficult for the boiling curve to escape the nose tip of most steel "C" curves; The second is that the bottom cooling rate is too fast, which causes greater stress on the workpiece during the ...

If it is an oil hardening steel, then it needs to be quenched (cooled through the martensite transition) fast enough to convert to martensite, and slow enough to minimize internal stresses. Water cools it too fast, so oil is used as a quench medium. Search terms heat treating steel brings up a very good Wikipedia article on heat treating. Keep ...

THE BASICS OF MOLTEN SALT QUENCHANTS

Quenching in water, brine, a water-based polymer solution, or oil can cause distortion and in some cases, nonuniform hardness or cracks. This tendency increases with increasing hardenability of the steel. Causes of distortion usually can be traced to un-even or nonuniform quenching, thermal stresses, and phase transfor-mation stresses.
