Description
Product introduction:
With the continuous development of vacuum heat treatment technology, vacuum quenching of workpieces is becoming more and more common. Vacuum quenching oil is a kind of quenching oil specially used in vacuum quenching furnace. It is composed of mineral base oil with high purity, low gas solubility and good anti-gasification performance and various special additives. KERUN® KR348 vacuum quenching oil has been widely used in molds, bearings, springs, oil pump nozzles and other industries.
Product Features:
1.Short distillation range, extremely low saturated vapor pressure, strong anti-vaporization ability, non-volatile, easy to vacuum
2.Good thermal oxidation stability which keeps long service life
3.Good brightness, low oil consumption and easy to clean
