Manufacturing Process & Heat Treatment of SS 347
Annealing
Annealing of SS 347 involves heating the material to a temperature range of 1000-1100°C, followed by controlled cooling. This process relieves internal stresses, enhances ductility, and improves overall mechanical properties, making the steel easier to work with during subsequent processing.
Forging
Forging of SS 347 is typically carried out at temperatures between 900-1200°C. This process involves shaping the metal through compressive forces, which align the grain structure, enhance strength, and improve toughness. It is essential for producing components with high strength-to-weight ratios.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil or Water | To increase hardness and strength by transforming austenite to martensite. |
| Tempering | 650-750 | Air | To relieve stresses and reduce brittleness while maintaining hardness. |
| Stress Relieving | 600-700 | Air | To minimize residual stresses from machining and forming processes. |
The manufacturing processes and heat treatment practices for SS 347 are crucial in achieving the desired mechanical properties and performance characteristics, ensuring that the final products meet industry standards and customer requirements.
