What is Inconel 625?
Inconel 625 is a nickel-chromium-molybdenum alloy known for its exceptional corrosion resistance and strength. The presence of molybdenum and niobium enhances its toughness and prevents localized corrosion, pitting, and crevice attack — even in severe environments.
This alloy performs efficiently across a wide temperature range — from cryogenic levels to 982°C (1800°F) — making it suitable for various industrial applications that require both mechanical strength and corrosion protection.
Chemical Composition of Inconel 625
| Element | Percentage (%) |
|---|---|
| Nickel (Ni) | 58.0 min |
| Chromium (Cr) | 20.0 – 23.0 |
| Molybdenum (Mo) | 8.0 – 10.0 |
| Niobium (Cb) + Tantalum (Ta) | 3.15 – 4.15 |
| Iron (Fe) | 5.0 max |
| Carbon (C) | 0.10 max |
| Manganese (Mn) | 0.50 max |
| Silicon (Si) | 0.50 max |
| Phosphorus (P) | 0.015 max |
| Sulfur (S) | 0.015 max |
This perfect blend of elements gives Inconel 625 its unique resistance to oxidation, scaling, and corrosion in extreme environments.
