NANJING KERUN LUBRICANTS CO., LTD.  

Product Name: Kerun Fast Quenching Oil Pr-L19 Model NO.: PR-L19 Usage: Machinery Appearance: Liquid Color: Yellow Environmental Protection: Yes Trademark: KERUN Transport Package: Bucket Specification: 165KG Origin: Nanjing, Jiangsu Product Description Product introduction:With the development of automobile, tractor manufacturing industry and large-scale mining equipment, the size and weight of heat-treated parts are increasing. In order to improve production efficiency, the quenching amount of primary parts is increasing, and continuous quenching automatic line is emerging, which leads to the development of high speed quenching oil. Fast quenching oil is quenching oil with additives added, and the cooling speed is faster than ordinary quenching oil. PR-L19 fast quenching oil is suitable for quenching of thick and large workpiece because of its short vapor film stage, high cooling speed and good hardenability.ProductFeatures:1.Short vaporfilm stage, cooling speed is higher than mechanicaloil with good hardenability. 2.Less oil consumption, reduces the production cost3.Stable cooling characteristic,long service life.4.High flash point, Small volatility.Product description:ItemPR-L19MethodMoisture≤0.03%ASTM D6304Flash point (open cup)≥165°CASTM D92Kinematic viscosity (40°C)12-18mm2/sASTM D7279Corrosion (Copper sheet 100°C×3h)≤1bASTM D130Thermal oxidation stability, viscosity ratio≤1.4SH/T 0219Cooling performanceCharacteristic temp.≥670°CISO9950(oil temp. 60°C, static)Max. cooling speed≥105°C
