Manufacturing Process & Heat Treatment of Super Duplex Spool
Annealing
Annealing of super duplex stainless steel spools involves heating the material to a temperature range of 1020°C to 1100°C, followed by air cooling. This process helps to relieve internal stresses, improve ductility, and homogenize the microstructure, ensuring a uniform distribution of phases.
Forging
The forging process for super duplex spools is performed at elevated temperatures between 1100°C and 1200°C. This hot working process enhances the mechanical properties of the material, resulting in improved strength and toughness. The forged spools are then subjected to controlled cooling to optimize their characteristics.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve ductility |
| Stress Relieving | 300 - 500 | Air | Eliminate residual stresses |
The combination of these manufacturing and heat treatment processes ensures that super duplex spools exported from Indonesia possess excellent mechanical properties and corrosion resistance, meeting international standards for quality and performance.
