A query about hardening of metal using quenching process. To get the hardness of 600 BHN the time span of 10 mins are required and want to reduce the time span of the work without affecting the hardness. The quenchant used is water. What changes should I make in the quenching process?
Thank you, that helps a lot. One last question, what is the purpose of quenching in the hardening process?
The purpose of quenching in the hardening process is to rapidly cool the metal after heating it to the austenite phase. During the heating process, the steel absorbs carbon atoms that dissolve in the austenite phase. When the metal is quenched, the austenite phase transforms into a harder phase called martensite, which contains the carbon atoms in a supersaturated state. The hardness of the resulting metal depends on the cooling rate, the carbon content, and the alloying elements present in the steel.
