Manufacturing Process & Heat Treatment of Duplex Steel Pipes
Annealing
The annealing process for duplex steel pipes involves heating the material to a temperature range of 1000°C to 1100°C. This process is essential for relieving internal stresses, improving ductility, and ensuring uniform microstructure. After heating, the pipes are slowly cooled in air to achieve the desired mechanical properties.
Forging
Forging of duplex steel pipes is conducted at elevated temperatures, typically between 900°C and 1200°C. This process enhances the strength and toughness of the material by refining the grain structure. The forging process involves shaping the steel through deformation, which increases its mechanical properties and ensures a high-quality end product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050 - 1150 | Oil | To increase hardness and strength |
| Tempering | 600 - 700 | Air | To relieve stresses and improve toughness |
| Stress Relieving | 300 - 500 | Air | To reduce residual stresses |
The combination of these processes ensures that duplex steel pipes meet stringent quality standards, offering excellent corrosion resistance and mechanical properties suitable for various industrial applications.
