Fast Quenching Oil KR118

KR118H
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 occur. KR118H Fast Quenching Oil, with a faster cooling rate than similar quenching oils, effectively addresses these problems. It provides high and uniform surface hardness along with sufficient hardened layer depth, ensuring superior quenching results for these challenging workpieces.

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, achieving 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.

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.
