Manufacturing Process & Heat Treatment of Duplex 2507
Annealing
Annealing of Duplex 2507 involves heating the material to a temperature range of 1020°C to 1100°C followed by controlled cooling. This process helps to relieve internal stresses and improve ductility, ensuring the material can withstand further processing without cracking.
Forging
Forging of Duplex 2507 is typically performed at temperatures between 1100°C and 1200°C. This hot working process enhances the mechanical properties of the steel by refining the grain structure, resulting in improved strength and toughness.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 800 | Air | Relieve residual stresses from prior processing |
The combination of these processes ensures that Duplex 2507 achieves optimal mechanical properties and corrosion resistance, making it suitable for a wide range of industrial applications.
