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
