Manufacturing Process & Heat Treatment of Super Duplex Flanges
Annealing
Annealing of super duplex flanges is performed to relieve internal stresses and improve ductility. The flanges are heated to a temperature range of 1020°C to 1100°C and held for a sufficient time to ensure uniform temperature throughout the material. This process enhances the corrosion resistance and mechanical properties of the flanges.
Forging
Forging is an essential step in the manufacturing of super duplex flanges, where heated billets are mechanically deformed to achieve desired shapes and dimensions. The forging temperature typically ranges from 1100°C to 1250°C, allowing the material to achieve optimal strength and toughness while minimizing defects.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stabilization | 800 - 900 | Air | Enhance resistance to stress corrosion cracking |
The combination of these manufacturing and heat treatment processes ensures that super duplex flanges produced in Bahrain meet the stringent quality standards required for global steel exports, providing exceptional performance in various industrial applications.
