Quenching: Process and Mediums | Steel | Metallurgy
Quenching oils, normally used are mineral oils and have viscosity around 100 SUS (Saybolt Universal Seconds) at 40°C. These oils cannot be used for shallow- hardening steels. Fast quenching oils have viscosity around 50 SUS at 40°C and are blended mineral oils and approach water-quenching power only in the initial stage of cooling.
