1 QUENCHING OILS The term quenching normally refers to the controlled cooling of steel components in a fluid to give specified properties. The hardness and the other physical properties obtained depend upon the composition of the steel, the dimension of the component, the time and temperature of the heat treatment and the speed and duration of the quenching process. A number of quenching mediums such as molten salts, brine solutions and synthetic quenchants can be used, but petroleum based quenching media find the widest application due to the following advantage. They are easier to control and give uniform hardness. Suitable for large scale automation These are non-corrosive and non-toxic. Metaquench grades have been specially formulated from highly refined petroleum oils with additives and have the following characteristics. Good thermal properties Good chemical and oxidation stability High boiling points and low volatility High flash and fire points Classification of Oils Based on GM Quenchometer SLOW OILS MEDIUM OILS FAST OILS METAOUENCH 39 = 14.6 s METAOUENCH 43 =12.1 s METAOUENCH 44 = 8.9 s METAOUENCH 42 = 14.2 s Page 1 of 9

2 HP METAQUENCH 39, 40 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. Meeting specifications: IS: (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. low volatility Page 2 of 9

3 HP METAQUENCH 42 General purpose compounded quenching oil suitable for quenching of components for conditions when higher quenching speeds are required. Meeting specifications: IS: (Re-affirmed in 1987) straight mineral type grade compounded. Application areas: General purpose quenching oil of all components. However, this oil is not suitable for quenching cyanided parts. Excellent wetting characteristics Page 3 of 9

4 HP METAQUENCH 43 This is general-purpose emulsifiable oil and forms milky white emulsion. Meets specifications: IS : 1115 and ZX of Indian defense Application areas: Suitable for all metals for machining operations where emulsifiable oil are normally used. The recommended concentration is between 5 to 10 % depending on the severity of machining. Sometimes used successfully for even grinding operations.
