INCONEL 625 is a nickel-based welding wire designed for high-strength, corrosion-resistant applications in extreme environments. It exhibits outstanding resistance to oxidation, pitting, and crevice corrosion, making it an excellent choice for offshore, nuclear power, and aviation industries. The balanced chemical composition of nickel (Ni), chromium (Cr), molybdenum (Mo), and niobium (Nb) ensures exceptional weldability and mechanical performance.
Chemical Composition
| Element | Ni | Cr | Mo | Fe | Nb+Ta | Co | Mn | Si | C | S | P |
|---|
| % | 58-63 | 20-23 | 8-10 | ≤5 | 3.15-4.15 | ≤0.5 | ≤0.5 | ≤0.5 | ≤0.1 | ≤0.015 | ≤0.02 |
This specific chemical composition ensures exceptional resistance to seawater exposure, high-temperature environments, and aggressive chemicals.
Key Features and Advantages
