Quenching oil is a process oil used as quenching medium.

The cooling capacity of oil is insufficient in the range of 550 ~ 650℃, and the average cooling rate is only 60 ~ 100℃/s, but in the range of 200 ~ 300℃, the slow cooling rate is very suitable for quenching.Oil is used for quenching alloy steel and small section carbon steel, which can not only obtain satisfactory hardenability and hardenability, but also prevent cracking and reduce deformation.
