Manufacturing Process & Heat Treatment of Duplex 2304 EFW Pipe
Annealing
Annealing of Duplex 2304 EFW Pipe is performed to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the material. The process involves heating the pipe to a temperature range of 1020°C to 1100°C, followed by controlled cooling, typically in air or furnace cooling. This treatment helps to refine the microstructure, ensuring optimal performance in various applications.
Forging
The forging process for Duplex 2304 involves shaping the material through compressive forces, which enhances its strength and toughness. The steel is heated to a forging temperature of approximately 1100°C to 1200°C, allowing it to be easily manipulated. This process is crucial for producing high-quality components with improved mechanical properties and reduced defects.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 400 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 500 | Air | Relieve residual stresses from manufacturing |
