GOLDENSTONE® MZ oils are designated for cold quenching of various types and contents steels.
These products are especially fit for bulk and surface quenching of high and low carbon steels. They are suitable for constructional and industrial alloyed steels. The well balanced additive package ensures high cooling rates in the pearlite and low cooling rates in the martensite intervals respectively. The treated parts are heated up to 800- 1100°С and then they are dipped in the oil. Thus they exhibit superior quenching depth and level of hardness of the material as well as very high cleanliness. The working temperature of the oil is between 30°C to 100°С. The higher the working temperature, the shorter the service life of the oil.
GOLDENSTONE® MZ quenching oils are formulated from highly refined paraffinic-naphthenic narrow cuts of low coking tendency blended with an appropriate high performance additive package to ensure excellent thermal & oxidation stability and cooling capacity to the oils and cleanliness of the treated parts.
