Manufacturing Process & Heat Treatment of Duplex S32205
Annealing
Annealing of Duplex S32205 is performed to relieve stresses induced during fabrication processes. The material is heated to a temperature range of 1020-1100°C and held for a sufficient time to ensure uniform temperature throughout the material. This process enhances ductility and reduces hardness, making it easier to work with in subsequent operations.
Forging
Forging of Duplex S32205 involves heating the steel to a temperature of approximately 1200-1300°C, followed by deformation to achieve the desired shape. This process improves the mechanical properties of the material through grain refinement and eliminates any porosity. The forged components are then air-cooled to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020-1100 | Oil | To increase hardness and strength |
| Tempering | 600-800 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 300-550 | Air | To relieve internal stresses from welding or machining |
The combination of these processes ensures that Duplex S32205 achieves optimal mechanical properties for its intended applications, providing excellent corrosion resistance and strength in various environments.
