What Is The Benefits Of Vacuum Hardening?

---

Vacuum hardening and ordinary hardening are two important processes for metal heat treatment, which play a vital role in improving the performance of metal materials and optimizing product structure. SIMUWU Vacuum Technology Co., Ltd., as a professional vacuum furnace manufacturer, has in-depth research and rich practical experience in the use of vacuum hardening furnaces.

Principle of vacuum hardening process

Vacuum hardening is an advanced heat treatment method that changes the internal structure of the material by heating and rapidly cooling the metal material in a vacuum environment, thereby improving its physical and mechanical properties. In contrast, although ordinary hardening is also a process of rapid cooling after heating, it is usually carried out in an atmospheric environment, so its process control and product quality may be affected by environmental factors.

Benefits of vacuum hardening

01 Environmental control

Vacuum hardening is carried out in a closed vacuum furnace, which effectively avoids adverse reactions between the material and oxygen, nitrogen, etc. in the air, and ensures the purity of the treatment process.

02 Temperature uniformity

In a vacuum environment, heating is more uniform, reducing the risk of material deformation and cracking.

03 Hardness and toughness

Vacuum hardening can significantly improve the hardness and toughness of the metal and extend the service life of the product.

Ordinary hardening

01 Environmental openness

Ordinary hardening is carried out in an atmospheric environment, and the metal surface may react with oxygen in the air, resulting in oxidation, decarburization and other undesirable phenomena.

02 Temperature control

Due to environmental factors, temperature control may not be as accurate as in a vacuum environment, which can easily lead to uneven material properties.

03 Cost considerations

Although the equipment cost is relatively low, due to the difficulty of quality control, more post-processing and inspection costs may be required.

Application scope of vacuum hardening

Vacuum hardening is an advanced heat treatment method that heats and rapidly cools metal materials in a vacuum environment to change the internal structure of the material and thereby improve its physical and mechanical properties. In contrast, although ordinary hardening is also a process of rapid cooling after heating, it is usually carried out in an atmospheric environment, so its process control and product quality may be affected by environmental factors.
