Material Description
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.
Core Properties of UNS N08810 (Incoloy 800H) Alloy
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.
Chemical Composition (Weight %)
| 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 |

Hot Rolled vs. Cold Drawn UNS N08810 Round Bars
| Feature | Hot Rolled UNS N08810 Round Bar | Cold Drawn (Bright Bar) UNS N08810 |
|---|---|---|
| Surface Finish | Black, scaled, or pickled; matte texture | Bright, smooth, mirror-like (Ra ≤ 0.8μm) |
| 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 |
Processing & Fabrication Capabilities
- Hot Working: Processable at 871-1232°C for forging, bending, and shaping
- Cold Working: Cold drawing enhances surface finish and dimensional accuracy
- Welding: Compatible with standard stainless steel welding techniques
- Machining: Machinable with carbide tools; coolant use recommended
Industrial Applications & Use Cases
- Chemical & Petrochemical: Sulfur-containing atmosphere equipment, condensers, and tubes
- Power Generation: Heat exchanger tubes, steam generator components, and gas turbine parts
- Nuclear Industry: Condenser systems and reactor auxiliary piping
- Manufacturing: Furnace fixtures, carburizing equipment, and heating element sheathing
Quality Assurance & Standards Compliance
Our UNS N08810 round bars adhere to global industry standards including ASTM B408 and ASME SB408. Each batch undergoes rigorous testing:
- Chemical analysis via X-ray fluorescence (XRF)
- Mechanical testing (tensile, yield, elongation)
- Non-destructive testing (ultrasonic for internal defects)
- Dimensional inspection with precision calipers
Why Choose UNS N08810 Over Alternatives?
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.
