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?
Would vegetable oil work?
Vegetable oil can work as a quenchant for some types of steel, but it has lower cooling capacity than water or mineral oil. For alloy steel with a high hardenability, you may need a quenchant with faster cooling rate.
