What is Heat Treatment?
Heat Treatment is a controlled process of heating and cooling metals to alter their microstructure and improve specific mechanical and physical properties.
Depending on the material and application requirements, heat treatment can be used to:
- Increase hardness
- Improve strength
- Enhance wear resistance
- Improve toughness
- Relieve internal stresses
- Increase fatigue resistance
- Improve dimensional stability
- Optimize machinability
Heat treatment is often performed before or after machining depending on the manufacturing process.
