Manufacturing Process & Heat Treatment of Duplex 2101 Flanges
Annealing
The annealing process for Duplex 2101 involves heating the steel to a temperature range of 1000°C to 1100°C, followed by controlled cooling. This treatment helps to relieve internal stresses, improve ductility, and refine the grain structure, ensuring uniform properties across the flange.
Forging
Forging of Duplex 2101 flanges is performed at elevated temperatures ranging from 1050°C to 1200°C. This process enhances the mechanical properties by aligning the grain structure of the material, resulting in increased strength and toughness. The forged flanges are then machined to meet precise specifications.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | To increase hardness and strength |
| Tempering | 400 - 600 | Air | To reduce brittleness and enhance toughness |
| Stress Relieving | 600 - 700 | Air | To relieve residual stresses from the manufacturing process |
The combination of these manufacturing and heat treatment processes ensures that Duplex 2101 flanges exhibit excellent mechanical properties, corrosion resistance, and durability, making them suitable for various industrial applications.
