PRODUCT DETAILS
Sinopec U8251 Isothermal Quenching Oil is based on secondary hydrorefined mineral oil, with various functional additives such as high-temperature antioxidants, cold reminder agents, and brighteners. It is applicable for small deformation of carburized steel, bearing steel, etc.
Applications:
Sinopec U8251 Isothermal Quenching Oil is suitable for use in:
- Both open quench tanks and enclosed quench tanks.
- Treating gears and bearings that require small amounts of deformation.
Features and Benefits:
- Moderately accelerated quenching characteristics: Fast cooling rate in the first and second stages of quenching, with excellent hardening capacity.
- Slow cooling rate in the third stage of quenching: Results in less deformation.
- Excellent oxidation resistance and thermal stability: Ensures a long lifetime and eliminates waste due to quench oil degradation.
