UNS N07750 / W.Nr. 2.4663 — Chemical composition, mechanical properties, and corrosion resistance data for engineers and procurement professionals.
Inconel X-750 (UNS N07750 / W.Nr. 2.4663) is a precipitation-hardenable nickel-chromium alloy with excellent corrosion and oxidation resistance up to 1300°F (704°C). The alloy gains its strength through gamma prime precipitation from additions of aluminum, titanium, and niobium.
The chemical composition of Inconel X-750 is carefully controlled to achieve its unique combination of properties and performance characteristics.
| Element | Min % | Max % |
|---|---|---|
| Nickel (Ni) | 70.0 | Balance |
| Chromium (Cr) | 14.0 | 17.0 |
| Iron (Fe) | 5.0 | 9.0 |
| Titanium (Ti) | 2.25 | 2.75 |
| Aluminum (Al) | 0.40 | 1.00 |
| Niobium+Tantalum (Nb+Ta) | 0.70 | 1.20 |
| Carbon (C) | — | 0.08 |
| Manganese (Mn) | — | 1.0 |
The mechanical properties of Inconel X-750 vary depending on product form and heat treatment condition. The data below represents typical values for solution-annealed material.
| Property | Value |
