Product Introduction
Vacuum quenching oil is a quenching oil specially used for vacuum furnaces. It has a short distillation range, low saturated vapor pressure, strong anti-vaporization ability, good thermal stability, and fast cooling speed. The cooling speed of A is higher than that of B. A is particularly suitable for quenching and tempering of carburized workpieces, and can also be used as a cooling oil for solution treatment of austenitic stainless steel. B is a milder cooling vacuum oil, similar to graded quenching oil. Users can choose according to the quenching requirements of the workpiece. The operating temperature is 20℃-80℃, and it is mainly used for workpieces quenched after vacuum heating. It can obtain good brightness, high and uniform quenching hardness and small quenching deformation.
