Manufacturing Process & Heat Treatment of Duplex Spool
Annealing
Annealing is a heat treatment process that involves heating the duplex stainless steel to a temperature range of 1000Β°C to 1100Β°C, followed by controlled cooling. This process helps to reduce hardness, improve ductility, and relieve internal stresses, resulting in enhanced machinability and improved mechanical properties.
Forging
The forging process for duplex spools involves heating the steel to approximately 1100Β°C to 1200Β°C and then applying mechanical force to shape it. This process enhances the strength and toughness of the material by refining the grain structure and eliminating porosity, ensuring a uniform and dense product.
Hardening & Tempering
| Process | Temperature Range (Β°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | Increase hardness and strength |
| Tempering | 400 - 600 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 500 - 700 | Air | Eliminate residual stresses |
The combination of these processes ensures that duplex spools achieve the desired mechanical properties and performance characteristics required for various applications in the industrial sector.
