Manufacturing Process & Heat Treatment of Duplex Sheets
Annealing
Annealing is a crucial heat treatment process that involves heating the duplex steel to a specific temperature, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and refine the microstructure of the material. Typically, duplex sheets are annealed at temperatures ranging from 1000°C to 1100°C, ensuring optimal mechanical properties and corrosion resistance.
Forging
Forging of duplex sheets involves shaping the metal through compressive forces, which enhances its strength and durability. This process is performed at elevated temperatures, allowing the material to be easily manipulated while maintaining its integrity. The forging process for duplex steels ensures uniform grain structure and mechanical properties, making them suitable for demanding applications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil or Water | To increase hardness and strength |
| Tempering | 400 - 800 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | To eliminate residual stresses from processing |
The combination of these manufacturing and heat treatment processes ensures that duplex sheets meet the rigorous standards required for various industrial applications, particularly in environments that demand high strength and corrosion resistance.
