Manufacturing Process & Heat Treatment of Super Duplex 2507 Flanges
Annealing
The annealing process for Super Duplex 2507 flanges 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, improve ductility, and enhance the overall mechanical properties of the steel.
Forging
Forging of Super Duplex 2507 involves shaping the metal using compressive forces, typically at elevated temperatures between 900°C to 1200°C. This process refines the grain structure, improves strength, and ensures a uniform distribution of alloying elements throughout the flange.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 600 | Air | Eliminate residual stresses |
The combination of these processes ensures that Super Duplex 2507 flanges possess the required mechanical properties and corrosion resistance for demanding industrial applications.
