Features of Incoloy 800HT polished N08811 bar
Excellent high-temperature performance:
Incoloy 800HT polished N08811 bar keeps high strength from 600°C to 900°C. It has excellent oxidation and creep resistance. This is because it has high nickel (30-35%) and chromium (19-23%).
Titanium and aluminum make the microstructure of Incoloy 800HT polished N08811 bar more stable. They stop high-temperature phase changes.
Corrosion resistance:
Incoloy 800HT polished N08811 bar resists oxidation, sulfidation and chloride stress corrosion. It works well in acidic, alkaline and sulfur-containing environments.
Machinability:
The polished surface of Incoloy 800HT polished N08811 bar lowers the friction coefficient. It reduces particle adhesion. It is good for precision part machining.
Stability:
The low carbon content (≤0.10%) of Incoloy 800HT polished N08811 bar reduces sensitization risk. It stays tough after long-term high-temperature use.
