Manufacturing Process & Heat Treatment of Super Duplex Spool
Annealing
Annealing of Super Duplex stainless steel spools is conducted at temperatures ranging from 1020Β°C to 1100Β°C. This process helps to relieve internal stresses, enhance ductility, and improve the overall microstructure of the material. The spools are then cooled slowly in air to achieve the desired mechanical properties.
Forging
The forging process involves heating the Super Duplex material to approximately 1150Β°C and then shaping it under mechanical pressure. This process improves the material's strength and toughness, creating a uniform grain structure that is essential for high-performance applications in corrosive environments.
Hardening & Tempering
| Process | Temperature Range (Β°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | To increase hardness and strength |
| Tempering | 600 - 800 | Air | To relieve stresses and improve toughness |
| Stabilization | 850 - 900 | Air | To enhance corrosion resistance and stability |
The combination of these processes ensures that Super Duplex spools meet the stringent requirements for high strength, corrosion resistance, and durability in challenging environments. Thorough quality control measures are implemented throughout the manufacturing process to guarantee the highest standards of performance.
