Manufacturing Process & Heat Treatment of SS 347H Hex Bolt
Annealing
Annealing of SS 347H hex bolts involves heating the material to a temperature of approximately 1050°C to 1100°C, followed by a slow cooling process. This treatment helps to relieve internal stresses, improve ductility, and enhance the overall mechanical properties of the steel, making it more workable for subsequent manufacturing processes.
Forging
Forging of SS 347H hex bolts is typically performed at elevated temperatures, around 950°C to 1200°C. This process involves shaping the heated steel using compressive forces, which results in improved grain structure, increased strength, and enhanced toughness. The forged bolts are then allowed to cool down naturally to room temperature.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 1020 - 1100 | Oil or Water | To increase hardness and strength |
| Tempering | 300 - 600 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 600 - 700 | Air | To relieve residual stresses from previous processes |
The combination of annealing, forging, and heat treatment processes ensures that SS 347H hex bolts meet the stringent requirements for strength, durability, and corrosion resistance necessary for various industrial applications.
