Manufacturing Process & Heat Treatment of Duplex 2304 EFW Pipe
Annealing
The annealing process for Duplex 2304 EFW pipes involves heating the material to a temperature range of 1000°C to 1100°C, followed by controlled cooling. This treatment helps to relieve internal stresses, enhance ductility, and improve the overall mechanical properties of the steel, ensuring better performance in industrial applications.
Forging
Forging of Duplex 2304 EFW pipes is performed at high temperatures, typically between 1050°C and 1200°C. This process involves shaping the material through compressive forces, which refines the grain structure, increases strength, and ensures uniformity in the final product. The forging process is crucial for achieving desired dimensional tolerances and enhancing the toughness of the material.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | To increase hardness and strength by rapid cooling |
| Tempering | 300 - 600 | Air | To reduce brittleness and relieve stresses after hardening |
| Stress Relieving | 600 - 700 | Air | To enhance ductility and toughness while minimizing residual stresses |
The combination of these manufacturing processes and heat treatments ensures that Duplex 2304 EFW pipes meet stringent quality standards and performance requirements for various industrial applications, making them a reliable choice for global steel exports.
