Manufacturing Process & Heat Treatment of Super Duplex Spool
Annealing
Annealing of super duplex stainless steel is performed to relieve stresses and improve ductility. The process involves heating the material to a temperature range of 1020-1100°C, followed by a controlled cooling to enhance the microstructure and reduce hardness.
Forging
Forging of super duplex spools involves shaping the material through deformation at elevated temperatures, typically between 1100-1250°C. This process improves the mechanical properties and ensures a uniform grain structure, which is crucial for high-strength applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil | Increase hardness and strength |
| Tempering | 600-800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 400-600 | Air | Minimize residual stresses |
The combination of these processes ensures that super duplex spools achieve optimal mechanical properties, making them suitable for demanding applications in various industries.
