Performance advantages:
        1. Low saturated vapor pressure, less evaporation under low pressure, strong anti-gasification ability, not easy to volatilize, easy to evacuate, and no pollution to the vacuum system;
        2. Low critical pressure (low pressure with the same quenching ability as atmospheric pressure), the cooling capacity does not change much with the decrease of air pressure, and there is still a certain cooling rate under vacuum;
        3. The surface brightness of the workpiece after quenching is high;
        4. Good chemical stability, long service life, less impurities and residual carbon, and low acid value.
 Main Application:
         Low saturated steam pressure, good cooling performance, good brightness, suitable for vacuum quenching of bearing steel, tool steel, large and medium-sized aviation structural steel and other materials. When first used, the air in the oil should be removed under vacuum. Operating temperature 20-80℃.
 Precautions:
       1. Prevent other debris from entering during storage. Do not mix with other oils.
        2. Avoid open flames near oil products.
        3. During use, maintenance and management should be strengthened, and degassing and dehydration treatment should be carried out regularly.
 Typical data:

Flash point℃		202
Kinematic viscosity 40℃ mm²/s		32.89
Moisture%		none
Copper sheet corrosion grade (100℃ 3h)		1
Thermal oxidation stability	Viscosity ratio	1.25
	Added value of residual carbon	1.25
cooling performance	Characteristic temperature      （80℃）	650
