Core Composition: The Foundation of Performance
The superior properties of Incoloy 800H stem from its precisely balanced chemical composition, which prioritizes high-temperature stability and corrosion resistance. Unlike generic alloys, its nickel-chromium-iron matrix is optimized with controlled additions of carbon, titanium, and aluminum to prevent sensitization and enhance creep strength.
| Element | Composition Range (%) | Key Function |
|---|---|---|
| Nickel (Ni) | 30.0 - 35.0 | Enhances stress corrosion cracking resistance and austenitic structure stability |
| Chromium (Cr) | 19.0 - 23.0 | Forms protective oxide layer for oxidation and carburization resistance |
| Iron (Fe) | ≥ 39.5 | Provides base strength and cost-effectiveness |
| Carbon (C) | 0.05 - 0.10 | Improves high-temperature creep and rupture strength |
| Titanium (Ti) | 0.15 - 0.60 | Stabilizes structure and prevents intergranular corrosion |
| Aluminum (Al) | 0.15 - 0.60 | Boosts oxidation resistance and forms coherent precipitates |
| Copper (Cu) | ≤ 0.75 | Limits impurities while maintaining alloy compatibility |
