IS:2664-1980(re-affirmed in 1987) straight mineral type grade medium and heavy respectively.
Application areas:METAQUENCH 39 is a general purpose quenching oil of all components including cyanided parts METAQUENCH 40 is a general purpose quenching oil of all components.
These are blends of refined base oils and contain no additives. METAQUENCH 39 is recommended for general purpose quenching of components and is particularly suitable for quenching of cyanided parts. METAQUENCH 40 is suitable in situations when lower quenching speed is desired.
Metaquench 39 is a general purpose oil for quenching of all components including cyanided parts. These are blends of highly refined base oils selected for their superior physical & chemical properties but contain no additives. These oils have in built resistance to oxidative, thermal and physical degradation. It can be used for normal quenching operations on a wide variety of steel parts such as nuts and bolts, ball bearings etc.
Metaquench 40 is recommended for quenching operation involving large components and higher temperatures. Being a higher viscosity oil with correspondingly higher thermal stability, it gives satisfactory performance with low oil consumption. These grades meet IS 2664:1980 Straight Mineral type Grade Medium and Heavy respectively.
- Good thermal conductivity
- Good oxidation stability low volatility
