Manufacturing Process & Heat Treatment of Duplex Spools
Annealing
Annealing of duplex spools is performed to relieve internal stresses and improve ductility. The process typically involves heating the material to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This treatment enhances the microstructure, promoting a balanced phase distribution between austenite and ferrite.
Forging
The forging of duplex spools is carried out at elevated temperatures, generally between 1100°C and 1200°C. This process involves shaping the metal through compressive forces, which refines the grain structure and improves mechanical properties. Post-forging, the spools are often subjected to a normalizing heat treatment to further enhance their strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | To increase hardness and strength by transforming the microstructure. |
| Tempering | 300 - 600 | Air | To reduce brittleness and improve toughness after hardening. |
| Stress Relieving | 500 - 800 | Air | To alleviate residual stresses from welding or machining. |
The combination of these processes ensures that duplex spools achieve optimal mechanical properties, making them suitable for a wide range of applications in harsh environments. Continuous monitoring and quality assurance measures are implemented throughout the manufacturing and heat treatment stages to maintain high standards.
