Manufacturing Process & Heat Treatment of SS 347 Hex Bolt
Annealing
Annealing of SS 347 hex bolts involves heating the material to a temperature of approximately 900-1100°C, followed by slow cooling. This process relieves internal stresses, improves ductility, and enhances the overall mechanical properties of the steel, making it more workable for further processing.
Forging
The forging process for SS 347 hex bolts is conducted at elevated temperatures, typically between 1000-1200°C. This method involves shaping the steel through compressive forces, which refines its microstructure, improves strength, and ensures uniformity in the material properties. After forging, the bolts undergo cooling to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1000-1100 | Oil or Water | To increase hardness and strength by forming martensite |
| Tempering | 600-800 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 400-600 | Air | To relieve residual stresses from the manufacturing process |
The combination of these manufacturing and heat treatment processes ensures that SS 347 hex bolts exhibit excellent corrosion resistance, high strength, and durability, making them suitable for various industrial applications.
