Manufacturing Process & Heat Treatment of SS 321
Annealing
Annealing of SS 321 involves heating the material to a temperature of approximately 1050°C to 1150°C, followed by a controlled cooling process. This treatment helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the steel. The process also helps in dissolving any precipitated carbides, ensuring a more uniform microstructure.
Forging
Forging of SS 321 is performed at elevated temperatures, typically between 900°C and 1200°C. This process involves shaping the steel through compressive forces, which enhances its strength and toughness. Forging also refines the grain structure, resulting in improved mechanical properties and performance in applications requiring high strength and corrosion resistance.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 980 - 1100 | Water or Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | Minimize internal stresses |
The combination of these manufacturing and heat treatment processes ensures that SS 321 sheets and coils exhibit excellent resistance to corrosion, high-temperature stability, and enhanced mechanical properties, making them suitable for a wide range of industrial applications.
