Key Advantages:
Low saturated vapor pressure ensures consistent quenching hardness in low-pressure conditions equivalent to normal atmospheric pressure, effectively maintaining the surface brightness of workpieces under oxidation-free heating conditions. It minimizes oil consumption and keeps workpieces clean.
Excellent cooling performance and rust prevention result in a smooth surface after quenching, guaranteeing the required surface hardness and specific metallographic structure of the quenched material.
Superior thermal oxidation stability ensures long-term stable brightness and optimal cooling characteristics, extending the service life of the oil.
Main Applications:
Suitable for vacuum quenching of medium-to-large structural steel, bearing steel, carburized steel, tool and mold steel, high-speed steel, and other alloy steels.
Precautions:
Store indoors. If outdoor storage is necessary, place the barrels horizontally to prevent water ingress and avoid submerging the barrel labels.
Avoid contamination with foreign substances, as this may cause oil deterioration or failure.
Do not mix with other oils to prevent performance degradation.
For materials prone to discoloration, such as Cr12, tempering should be conducted in a protective atmosphere. It is not recommended to temper in an electric heating furnace.
