Manufacturing Process & Heat Treatment of Duplex Steel Sheets
Annealing
The annealing process for duplex steel sheets involves heating the material to a temperature range of 1000°C to 1100°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the steel. The aim is to achieve a balanced microstructure of austenite and ferrite, which is characteristic of duplex stainless steels.
Forging
Forging of duplex steel sheets is performed at elevated temperatures, typically between 900°C to 1200°C. This process enhances the strength and toughness of the material by refining the grain structure. The controlled deformation during forging allows for improved mechanical properties and better performance in various applications, including the oil and gas industry.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Water or Oil | To increase hardness and strength |
| Tempering | 300 - 600 | Air | To relieve stresses and improve ductility |
| Stress Relieving | 500 - 700 | Air | To reduce residual stresses after welding or machining |
The manufacturing and heat treatment processes for duplex steel sheets are crucial in ensuring the material meets the stringent requirements of various industrial applications. By optimizing these processes, we achieve superior mechanical properties and enhanced corrosion resistance, making our duplex steel sheets suitable for global export.
