Manufacturing Process & Heat Treatment of Super Duplex 2507 Flanges
Annealing
Annealing of Super Duplex 2507 flanges is performed to relieve internal stresses and improve ductility. The flanges are heated to a temperature of approximately 1020°C to 1100°C and held for a sufficient duration to allow for uniform temperature distribution. This process helps to enhance the mechanical properties and ensures a finer microstructure.
Forging
The forging process for Super Duplex 2507 involves heating the raw material to a temperature range of 1100°C to 1200°C. This allows for the material to be shaped into flanges through various mechanical processes such as hammering or pressing. Forging enhances the strength and structural integrity of the flanges by refining the grain structure.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 600 | Air | Eliminate residual stresses |
The careful application of these manufacturing and heat treatment processes ensures that Super Duplex 2507 flanges exhibit superior mechanical properties, making them suitable for various demanding applications in industries such as oil and gas, marine, and chemical processing.
