Heat treatment is a process that involves heating, holding, and cooling metal or alloy to change its microstructure and properties to meet different application requirements. It does not alter the overall shape of the metal but significantly enhances its mechanical properties, wear resistance, corrosion resistance, and service life.
The primary purpose of heat treatment is to improve the performance of metal materials to meet specific processing or usage requirements. The key reasons include:
Increase hardness (e.g., quenching improves steel hardness)
Improve strength (e.g., quenching and tempering enhance tensile strength)
Increase toughness (e.g., annealing reduces brittleness and increases ductility)
Enhance wear resistance (e.g., surface hardening improves wear resistance for gears, bearings, etc.)
Makes metal easier to cut and machine (e.g., normalizing refines grains and improves machinability)
Reduces internal stress to prevent deformation and cracking (e.g., annealing eliminates residual stress caused by cold working or welding)
Solution treatment for stainless steel improves corrosion resistance
Heat treatment enhances high-temperature strength, making materials suitable for boilers, jet engines, etc.
Refines metal grains for better uniformity
Corrects internal defects such as shrinkage cavities and segregation, enhancing material reliability
| Heat Treatment Method | Main Purpose |
|---|---|
| Annealing | Reduces hardness, increases ductility, and eliminates internal stress |
| Normalizing | Refines grain structure, improves strength and toughness |
| Quenching | Increases hardness and wear resistance |
| Tempering | Reduces brittleness after quenching, increases toughness |
| Quenching + Tempering | Balances strength and toughness for comprehensive mechanical performance |
| Carburizing | Increases surface hardness and wear resistance |
| Solution Treatment | Enhances corrosion resistance, mainly for stainless steel and aluminum alloys |
Machinery Manufacturing (gears, bearings, cutting tools, molds)
