Manufacturing Process & Heat Treatment of Duplex 2205 Pipe
Annealing
Annealing of Duplex 2205 pipes is performed to relieve internal stresses and enhance ductility. The process involves heating the pipes to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This treatment helps in achieving a balanced microstructure of austenite and ferrite phases, which is essential for optimal mechanical properties.
Forging
The forging of Duplex 2205 involves shaping the metal through mechanical deformation at high temperatures, typically between 1100°C and 1200°C. This process improves the material's strength and toughness by refining the grain structure and eliminating defects from casting.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | To increase hardness and strength by forming martensite. |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve toughness after hardening. |
| Stress Relieving | 300 - 600 | Air | To relieve residual stresses from machining and welding processes. |
The combination of these manufacturing and heat treatment processes ensures that Duplex 2205 pipes achieve the necessary mechanical properties and corrosion resistance required for demanding applications in various industries.
