Ultra-fast Quenching oil KR105
KR105
When using conventional quenching oils for thick, large workpieces or those with low hardenability, issues such as soft spots, low hardness, and insufficient hardened layer depth often arise. KR105 Over speed Quenching Oil, with a faster cooling rate than similar quenching oils, effectively addresses these issues. It enables the workpieces to achieve high and uniform surface hardness, along with sufficient hardened layer depth.
Product Details
Advantages
Short Vapor Film Phase, Fast High and Medium-Temperature Cooling Rates, and Appropriate Low-Temperature Cooling Rate: | Suitable for medium to large workpieces, providing high and uniform surface hardness and sufficient hardening depth while effectively controlling quenching deformation. | Good Thermal Oxidation Stability and Long Service Life. | Stable Performance, Low Oil Carry-Off, and Low Usage Cost.
Technical Specifications
| Model | KR105 |
|---|---|

| Application Range | Ideal for rapid cooling of medium to large alloy steel parts and carburizing quenching of similar size low-carbon alloy steel, particularly where core structure and hardness are critical. |
Storage Conditions
| Item | Requirements |
| Storage Temperature | 5–40°C. Indoor storage is recommended. Protect from freezing, as freezing may damage the polymer system. |
| Packaging & Container Requirements | Packaged in 200 L plastic drums with a net weight of 200 kg per drum; 25 kg plastic pails or 1,000 kg intermediate bulk containers (IBCs) may also be used. |
| Shelf Life | 2 years. After expiry, the product may only be used after it has been retested and confirmed to meet specifications. |
| Key Properties (KR9988) | Appearance: light yellow to pale red viscous liquid; pH (5% solution): 9.5–10.5; kinematic viscosity (10% solution at 40°C): 3.19 mm²/s. |
| Precautions | Nonflammable and presents no fire hazard; nevertheless, keep the container tightly sealed. If stored outdoors, place the drum horizontally to prevent water, dust, and other contaminants from entering. Retighten the cap immediately after dispensing. Check the concentration with a refractometer before use. PAG-containing products exhibit reverse solubility; polymer separation at elevated temperatures is normal, and the product can be restored by cooling and stirring. |
