Manufacturing Process & Heat Treatment of Duplex Steel Sheets
Annealing
Annealing of duplex steel sheets involves heating the material to a temperature range of 950°C to 1100°C, followed by controlled cooling. This process helps to reduce hardness, improve ductility, and relieve internal stresses, ensuring optimal mechanical properties for subsequent processing and applications.
Forging
Forging of duplex steel sheets is typically conducted at temperatures between 1000°C to 1200°C. This process enhances the strength and toughness of the material by refining the grain structure, resulting in improved performance characteristics suitable for various industrial applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | Increase hardness and strength |
| Tempering | 300 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Eliminate residual stresses from manufacturing |
The combination of these processes ensures that duplex steel sheets produced for export meet the highest standards of quality and performance, making them suitable for a wide range of applications across various industries.
