Heat Treatment
Vacuum Heat Treatment
- The process changes metals in the vacuum device based vacuum state, and improves toughness, strength, and hardness of parts without deformation.
- Vacuum heat treatment includes metal annealing, dipping, and tempering in vacuum state.
- Vacuum heating causes degassing so that it is possible to make quality products.
- It is suitable for brilliance annealing of stainless steel, Ti alloy, and silicon steel plate.
- Vacuum Heat Treatment is a sort of new heat treatment method.
Advantages and Features
- Excellent surface brilliance
- Purifying effect, Prevention of oxidation & decarburization
- Minimal heat treatment deformation
- Eco-friendly processing

Gas Nitriding
- Unlike carburizing and high-frequency heating, it uses around 500℃ heating in NH3 air current to inject N on the surface in order to generate the hardening layer of nitriding. After that, there is no need of quenching.
- The process to improve corrosion-resistance and fatigue-resistance of parts
Advantages and Features
- Improvements in corrosion-resistance and fatigue-resistance of various parts and materials
- Free adjustment of compound layer by nitrogen potential
