Product Description
Isorapid 566 is a true high performance and multi-purpose quenching oil developed by Petrofer. It can be used not only in the oil temperature range of 60-80 °C in cold oil, but also it can be used at 120 °C because of its extremely high flash point. The maximum operating temperature can reach 220 °C, which can be used as a graded quenching oil.

At the beginning of cooling, it exhibits a shorter vapour phase, using the ISO9950- compliant Nickel-alloy probe test. The cooling curve shows that the rupture temperature of Isorapid 566 vapour phase can reach above 800 °C. The temperature range of the conventional rapid quenching oil and the graded quenching oil is generally in the range of 680-720 °C. The extremely vapour phase is very close to the ideal cooling performance with little steam film, ensuring the ideal quenching effect of quenching parts to achieve uniform fast cooling at high temperatures.

Available Packaging
180 kg Drum

Benefits

Provides a high rate of cooling in the initial phase of quenching
Produce a high and uniform yield hardness and minimum distortion
Has a fast cooling rate and maximum boiling cooling rate in the middle temperature phase
Does not influence a protective or carburizing atmosphere

Applications

Widely used and can be used in both protective atmospheres and open oil tanks
Use for quenching alloyed as well as lean-alloyed or plain carbon steel, such as isothermal quenching of various saw blades and gears, bearing rings and other extremely high requirements distortion
May also be used to quench work from all kinds of salt baths
