Material Description
Incoloy 800H (UNS N08810) round bars with bright polish finish represent the pinnacle of high-performance alloy engineering. These premium stainless steel bars deliver uncompromising performance in extreme environments while maintaining exceptional aesthetic quality.
Chemical Composition
The exceptional characteristics of Incoloy 800H (UNS N08810) stem from its precisely balanced chemical composition, ensuring stability across a wide temperature range and resistance to oxidation, carburization, and creep deformation.
| Element | Composition Range (%) | Primary Function |
|---|---|---|
| Nickel (Ni) | 30.0 - 35.0 | Maintains austenitic structure at high temperatures; prevents embrittlement |
| Chromium (Cr) | 19.0 - 23.0 | Forms protective oxide layer; resists oxidation and corrosion |
| Iron (Fe) | Balance | Provides structural base while optimizing cost-efficiency |
| Carbon (C) | 0.05 - 0.10 | Enhances creep strength through carbide formation |
| Aluminum (Al) | 0.15 - 0.60 | Works with titanium to form strengthening precipitates |
| Titanium (Ti) | 0.15 - 0.60 | Stabilizes carbide formation; Al+Ti sum controlled at 0.85-1.20% |
| Manganese (Mn) | ≤1.50 | Aids in deoxidation during manufacturing |
| Silicon (Si) | ≤1.00 | Improves high-temperature oxidation resistance |
| Sulfur (S) | ≤0.015 | Minimized to prevent hot working issues |
| Phosphorus (P) | ≤0.030 | Controlled to avoid brittleness |
