Hastelloy X vs 718 Comparison At the molecular level, the fundamental difference between Hastelloy X and Inconel 718 lies in their strengthening mechanisms. Hastelloy X is a solid-solution strengthened alloy (predominantly Nickel-Chromium-Iron-Molybdenum), whereas Inconel 718 is a precipitation-hardenable (age-hardened) alloy. Inconel 718 contains significant amounts of Niobium (Nb) and Titanium (Ti), which form gamma prime (\u03b3\u2032) and gamma double-prime (\u03b3\u2032\u2032) precipitates.
