Product 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® KR328 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
