Product Name: Kerun Fast Quenching Oil Kr118h Model NO.: KR118H Usage: Machinery Appearance: Liquid Color: Black Environmental Protection: Yes Trademark: KERUN Transport Package: Bucket Specification: 165KG Origin: Nanjing, Jiangsu Product Description Product introduction: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. Kerun's fast quenching oil has strong cooling capacity, high temperature cooling speed and moderate low temperature cooling speed, which can not only make the workpieces obtain high and uniform surface hardness and enough hardening layer depth, but also can better control the quenching deformation, and the surface of the workpieces after quenching is easy to clean, with good thermal oxidation stability and long service life. If common quenching oil is used for thick and large workpieces or workpieces with poor hardness, problems could occur such as soft spots, low hardness and insufficient depth of hardening layer. The KR118H high speed quenching oil is faster in cooling speed and more stable in performance, which avoids the above problems, and obtains high and uniform surface hardness and enough depth of the hardened layer.ProductFeatures:Short vaporfilm stage, fast cooling at high and medium temperature stage, and has an appropriatecooling atlow temperature stage.For medium and large workpieces, high and uniform surface hardness and enough hardened depth can be obtained, and the deformation of workpiece can also be well controlled.Goodthermal oxidation stability and long service life.Stable performance, low oil consumption and low use cost.Product description:ItemKR118HMethodMoisture≤0.03%ASTM D6304Flash point (open cup)≥170°CASTM D92Kinematic viscosity (40°C)13-23mm2/sASTM D7279Corrosion (Copper sheet 100°C×3h)≤1ASTM D130Acid value≤0.3mgKOH/gASTM D664Thermal oxidation stabilityviscosity ratio≤1.25SH/T 0219Cooling performanceCharacteristic temperature≥680°CISO9950(60°C, static)Max. typical cooling rate110°C/s
