Manufacturing Process & Heat Treatment of SS 347H
Annealing
Annealing of SS 347H is performed to relieve internal stresses and improve ductility. The process involves heating the material to a temperature range of 1000°C to 1100°C, followed by controlled cooling. This ensures a uniform microstructure and enhances the mechanical properties of the final product.
Forging
Forging of SS 347H involves shaping the metal through compressive forces, typically at elevated temperatures. This process enhances the strength and toughness of the material by refining its grain structure. The forging temperature generally ranges from 900°C to 1200°C, allowing for optimal workability and performance.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1040 - 1100 | Oil | Increase hardness and strength |
| Tempering | 600 - 800 | Air | Reduce brittleness and improve toughness |
| Stress Relieving | 300 - 500 | Air | Eliminate residual stresses |
The combination of annealing, forging, and heat treatment processes ensures that SS 347H nut bolts exhibit excellent mechanical properties, corrosion resistance, and durability, making them suitable for various industrial applications.
