UNS N08810, commonly designated as Incoloy 800H, is a premium nickel-iron-chromium alloy round bar engineered for exceptional performance in high-temperature and corrosive environments. Available in hot rolled and cold drawn (bright bar) variants, this alloy combines robust mechanical strength, superior corrosion resistance, and structural stability—making it a cornerstone material in industries demanding reliability under extreme conditions.
The exceptional performance of UNS N08810 stems from its precisely balanced chemical composition and austenitic face-centered cubic lattice structure. Its controlled carbon content (0.05-0.10%) and optimized aluminum-titanium ratio enhance creep resistance and structural stability at elevated temperatures.
| Element | Minimum | Maximum | Role |
|---|---|---|---|
| Nickel (Ni) | 30.0 | 35.0 | Enhances stress corrosion cracking resistance |
| Chromium (Cr) | 19.0 | 23.0 | Provides oxidation and corrosion resistance |
| Iron (Fe) | Balance | Balance | Base metal ensuring structural integrity |
| Carbon (C) | 0.05 | 0.10 | Improves high-temperature creep strength |
| Manganese (Mn) | - | 1.50 | Aids in hot workability |
| Silicon (Si) | - | 1.00 | Supports oxide film formation |
| Copper (Cu) | - | 0.75 | Minimized to avoid compatibility issues |
| Sulfur (S) | - | 0.015 | Reduced to prevent brittleness |
| Aluminum (Al) | 0.15 | 0.60 | Enhances oxidation resistance |
| Titanium (Ti) | 0.15 | 0.60 | Stabilizes austenitic structure |
| Property | Specification | Notes |

| Diameter Range | 10-200mm (standard); larger sizes on request | 3-100mm; tighter tolerances |
| Dimensional Tolerance | ±0.5mm | ±0.1mm |
| Mechanical Properties | Moderate hardness; excellent ductility | Higher hardness (150-180 HB); enhanced tensile strength |
| Key Advantages | Cost-effective; ideal for heavy machining | Ready for direct assembly; reduces post-processing |
| Typical Applications | Furnace components, structural supports | Precision shafts, valve stems, instrument parts |
Our UNS N08810 round bars adhere to global industry standards including ASTM B408 and ASME SB408. Each batch undergoes rigorous testing:
Compared to similar alloys like UNS N08811 (Incoloy 800HT), UNS N08810 offers a cost-effective balance of performance for applications below 700°C. Its resistance to sulfur-containing atmospheres makes it preferable to 304 stainless steel in chemical processing applications.
Whether your project requires the cost-efficiency of hot rolled bars or the precision of cold drawn bright bars, UNS N08810 (Incoloy 800H) round bars provide reliable performance in challenging environments.
