Manufacturing Process & Heat Treatment of Duplex Steel Sheets
Annealing
Annealing of duplex steel sheets involves heating the material to a temperature range of 1020°C to 1100°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, improve ductility, and enhance the material's toughness, making it suitable for various industrial applications.
Forging
Forging is performed at temperatures between 1200°C and 1300°C, where the duplex steel is shaped under high pressure. This process refines the grain structure and enhances the mechanical properties, resulting in sheets that exhibit improved strength and durability.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stabilization | 850 - 900 | Air | Enhance corrosion resistance and stabilize microstructure |
The manufacturing and heat treatment processes are crucial in producing high-quality duplex steel sheets that meet international standards for strength, durability, and corrosion resistance, making them ideal for various applications in the global market.
