Redefining Quenching Technology

As metallurgical technology seeks to ever-improve and provide heat treating solutions, dry gas quenching stands out as the best match for industry needs. Gas quenching has several noteworthy benefits compared to other quench systems. It is the only dry quenching that exists and, therefore, eliminates all environmental or safety problems connected with liquid quenching. It is not only the safest and most environmentally friendly system, but it is also the system that produces the least distortion.

In this paper, authors examine why defining gas quenching in bar pressure no longer applies and a new set of definitions are needed, as well as how this new definition will allow for a better understanding of which steel and cross-section can be hardened in gas. Additionally, they will discuss results from studies regarding quenching chamber design, material cross-section and quenching in liquid or gas.
