What is oil quenching?

Oil quenching consists in heating the steel above the critical temperature Ac3 or Ac1, after soaking for a certain period of time, the workpiece is quickly placed in oil, and the process of cooling to room temperature is called oil quenching.

Oil quenching is the most common quenching process and plays a very important role in the heat treatment of steel, the cooling rate of oil quenching is between gas quenching and water quenching. For some alloy steel parts, oil quenching can provide higher hardness at hardening.

Vacuum Oil Quenching Furnace

What is air cooling? What is the difference with oil quenching?

Definition: After vacuum heating is completed, it is transferred to a cooling chamber where the air is cooled until it cools down to room temperature.

Features: 1. It is suitable for materials with low critical martensite cooling rate, such as high speed steel, high carbon and high chromium steel.

2.It is suitable for complex-shaped small parts, not easy to deform and split.

Differences: 1. Air cooling can be used separately. During the oil quenching process, the oil surface must be inflated to suppress the oil surface, so as to reduce the concentration of oil mist (combustible gas) in the air-cooled room and improve the oil quenching effect.

2. The internal stress in the air-cooled workpiece is small, the hardness is slightly lower, but the deformation is small.

3. Air cooling and oil quenching are complementary, one vacuum oil quenching is less, and inert gas must be introduced to improve the cooling capacity of vacuum quenching oil.
