Manufacturing Process & Heat Treatment of Gunmetal Round Bar
Annealing
Annealing of gunmetal round bars is conducted to relieve internal stresses and improve machinability. The bars are heated to a temperature range of 400-600°C, followed by slow cooling. This process enhances ductility and reduces hardness, making the material easier to work with in subsequent manufacturing processes.
Forging
Forging is performed at elevated temperatures, typically between 700-900°C. The gunmetal is shaped into round bars through mechanical deformation, which aligns the grain structure and improves strength. This process ensures that the final product exhibits superior mechanical properties and durability.
Hardening & Tempering
| Process | Temperature Range (°C) | Quenching Medium | Purpose |
|---|---|---|---|
| Hardening | 850-950 | Water or Oil | To increase hardness and strength |
| Tempering | 300-500 | Air | To reduce brittleness and improve toughness |
| Stress Relieving | 200-300 | Air | To minimize residual stresses |
The combination of these processes ensures that our gunmetal round bars meet the stringent requirements of various industrial applications, providing excellent wear resistance and mechanical performance.
