Manufacturing Process & Heat Treatment of Duplex 2304 EFW Pipe
Annealing
Annealing of Duplex 2304 EFW pipes is performed to relieve internal stresses and enhance ductility. The pipes are heated to a temperature range of 1020-1100°C and held for a sufficient time to allow for the homogenization of microstructure. This process improves the overall corrosion resistance and mechanical properties of the steel.
Forging
Forging of Duplex 2304 involves heating the steel to a temperature range of 1100-1200°C, followed by deformation under compressive forces to achieve the desired shape. This process refines the grain structure and enhances the mechanical properties, making the material suitable for high-strength applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Water / Oil | To increase hardness and strength |
| Tempering | 600-800 | Air | To reduce brittleness and enhance toughness |
| Stress Relieving | 300-400 | Air | To alleviate residual stresses after machining |
The combination of these manufacturing and heat treatment processes ensures that Duplex 2304 EFW pipes exhibit exceptional mechanical properties and corrosion resistance, making them suitable for various industrial applications, especially in the oil and gas sector.
