What do the Tempering and Aging Functions of The Heat Treatment Furnace Refer To?

The heat treatment furnace has good structure to realize tempering function and aging function for different steel material.

Quenching and tempering function

Operation method: High temperature tempering after quenching is called quenching and tempering, which means heating the steel part to a temperature 10-20 degrees higher than that during quenching, holding it for quenching, and then tempering at a temperature of 400-720 degrees in the furnace.

Purpose: 

1. Improve cutting performance and enhance the smoothness of the machined surface; 

2. Reduce deformation and cracking during quenching; 

3. Obtain good comprehensive mechanical properties.

Application points: 1. Suitable for alloy structural steel, alloy tool steel, and high-speed steel with high hardenability; 2. It can not only be used as the final heat treatment for various important structures, but also as a preheat treatment for certain tight parts such as screws to reduce deformation.

Aging function

Operation method: Heat the steel part to 80-200 degrees in the furnace, keep it warm for 5-20 hours or longer, and then remove it from the furnace and cool it in the air.

Purpose: 

1. Stabilize the microstructure of quenched steel parts and reduce deformation during storage or use; 

2. Reduce internal stress after quenching and grinding, stabilize shape and size.

Application points: 1 Suitable for all types of steel after quenching; 2. Commonly used for tight workpieces that require no further shape changes, such as tight screws, measuring tools, bed frames, etc.
