The vacuum oil produced by Huifeng Enterprise is made of high-quality base oil and imported additives. It is an ideal lubricating material and is widely used in my country's military enterprises, display industry, lighting industry, solar energy industry, coating industry, refrigeration industry, aerospace, etc.
※ Lower saturated vapor pressure, smaller evaporation, allowing dissolved gas to escape quickly.
※ Strong anti-vaporization ability and faster cooling speed, no pollution to vacuum furnace and vacuum operation effect.
※ Stable cooling performance, under vacuum conditions, can ensure good hardening effect of workpiece after quenching.
※ Good brightness, clean and bright surface after quenching, no discoloration, no oxidation, no pollution.
※ Excellent volatility stability and oxidation stability, long service life.
※ Low saturation vapor pressure, small evaporation and rapid degassing.
※ Good anti-gasification ability and high cooling rate with no pollution to vacuum furnace and keep a good operation effect.
※ Stable cooling characteristic to ensure hardened property of workpiece after quenching.
※ Desirable bright characteristics, good surface finish with no oxidation. pollution or color change after quenching.
※ Excellent volatility and oxidation stability to keep a long service life.
※ Suitable for bearings, dies, tools, large and medium-sized aviation structural steels and other special steels.
※ HFV-CZ0 vacuum quenching oil is used for quenching materials with poor hardenability under vacuum.
※ HFV-CZ1 vacuum quenching oil is used for quenching medium-sized materials under vacuum.
※ HFV-CZ2 vacuum quenching oil is used for quenching materials with good hardenability under vacuum.
※ Applicable to bearings, tools and dies, cutters, aviation structural steel and other special steel products.
※ HFV-CZ0 can be used to materials with poor quenching property if vacuum quenching.
※ HFV-CZ1can be used middle-size materials if vacuum quenching.
※ HFV-CZ2 can be used to materials with good quenching property if vacuum quenching.
