Material Description
Chemical Composition of Monel K500
Monel K500's remarkable corrosion resistance and strength are due to its carefully balanced chemical composition:
| Element | Percentage Range |
|---|---|
| Nickel (Ni) | 63.0% - 70.0% |
| Copper (Cu) | 28.0% - 33.0% |
| Iron (Fe) | 2.5% Max |
| Manganese (Mn) | 1.0% Max |
| Carbon (C) | 0.30% Max |
| Silicon (Si) | 0.50% Max |
| Sulfur (S) | 0.024% Max |
| Phosphorus (P) | 0.02% Max |
| Aluminum (Al) | 2.3% - 3.15% |
Monel K500's composition is primarily based on nickel and copper, with additions of aluminum and titanium, which significantly improve its hardness and strength without compromising its corrosion resistance. The alloy also features good resistance to stress-corrosion cracking, making it highly durable in hostile environments.
