Manufacturing Process & Heat Treatment of Super Duplex 32750 Sheet
Annealing
Annealing of Super Duplex 32750 sheets is performed to relieve internal stresses and improve ductility. The process typically involves heating the material to a temperature range of 1020-1080°C (1868-1976°F) followed by a controlled cooling process. This heat treatment enhances the microstructure, allowing for optimal corrosion resistance and mechanical properties.
Forging
Forging of Super Duplex 32750 is carried out to enhance its mechanical properties and achieve the desired shape. The material is heated to approximately 1100-1200°C (2012-2192°F) and then mechanically deformed. This process improves the grain structure and increases the strength of the final product.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1050-1150 | Water or Oil | To increase hardness and strength |
| Tempering | 300-500 | Air | To reduce brittleness and increase toughness |
| Stress Relieving | 600-750 | Air | To alleviate residual stresses from prior processing |
The manufacturing and heat treatment processes for Super Duplex 32750 sheets are critical in achieving the desired mechanical properties and corrosion resistance, making it suitable for demanding applications in various industries.
