Manufacturing Process & Heat Treatment of Super Duplex 32750
Annealing
The annealing process for Super Duplex 32750 involves heating the material to a temperature range of 1020°C to 1100°C, followed by controlled cooling. This process helps to relieve internal stresses, improve ductility, and enhance overall material properties, making it suitable for further processing.
Forging
Forging of Super Duplex 32750 is typically performed at temperatures between 1100°C and 1200°C. This hot working process improves the mechanical properties of the material by refining its microstructure, ensuring excellent strength and toughness, which are crucial for demanding applications in corrosive environments.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Water or Oil | To increase hardness and strength |
| Tempering | 600 - 800 | Air | To reduce brittleness and improve toughness |
| Solution Treatment | 1020 - 1100 | Water | To dissolve precipitates and enhance corrosion resistance |
The combination of these processes ensures that Super Duplex 32750 sheets meet the stringent requirements for high-performance applications, delivering excellent resistance to pitting, crevice corrosion, and stress corrosion cracking.
