With the continuous development of vacuum heat treatment technology, vacuum quenching has become increasingly common for workpieces. KR328 vacuum quenching oil has been widely applied in industries such as tool and die, bearings, springs, and oil pumps and nozzles.
Advantages
● Short distillation range, low saturated vapor pressure, strong anti-vaporization ability, low volatility, and easy to vacuum.
● Good brightness, easy to clean, with minimal oil carry-over.
● Excellent thermal oxidation stability, providing a long service life.
