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 of approximately 1020°C to 1100°C. This process helps to reduce residual stresses, improve ductility, and enhance the overall mechanical properties of the alloy. After the heating phase, the flanges are rapidly cooled to room temperature, which further stabilizes the microstructure.
Forging
Forging of Super Duplex 2507 flanges is performed at temperatures ranging from 1050°C to 1150°C. The process involves shaping the raw steel through deformation under compressive forces. This method improves the mechanical properties of the material by refining the grain structure and achieving better strength and toughness in the final product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 800 | Air | Minimize residual stresses |
The combination of these processes ensures that Super Duplex 2507 flanges exhibit excellent mechanical properties, corrosion resistance, and durability, making them suitable for various industrial applications.
