ASTM B514 Incoloy 800 / Incoloy 800H UNS N08800 / UNS N08810 Welded Pipe
What is Incoloy 800/800H Welded Pipe?
Incoloy 800 (UNS N08800) and Incoloy 800H (UNS N08810) are nickel-iron-chromium superalloys known for their excellent resistance to oxidation, carburization, and high-temperature corrosion. These alloys are widely used in welded pipe form for applications in petrochemical, power generation, heat treatment, and chemical processing industries.
Key Features:
High-Temperature Strength: Maintains mechanical properties at
elevated temperatures (up to 1100°F / 593°C for 800H).
Oxidation & Corrosion Resistance: Resists oxidation, carburization, and sulfidation in harsh environments.
Good Fabricability: Can be welded and formed using standard techniques.
Stability: Resists stress corrosion cracking and chloride-ion attack.
Chemical Composition
| Element | Incoloy 800 (N08800) (%) | Incoloy 800H (N08810) (%) |
| Nickel (Ni) | 30.0 - 35.0 | 30.0 - 35.0 |
| Chromium (Cr) | 19.0 - 23.0 | 19.0 - 23.0 |
| Iron (Fe) | Balance | Balance |
| Carbon (C) | ≤ 0.10 | 0.05 - 0.10 |
| Aluminum (Al) | 0.15 - 0.60 | 0.15 - 0.60 |
| Titanium (Ti) | 0.15 - 0.60 | 0.15 - 0.60 |
| Manganese (Mn) | ≤ 1.50 | ≤ 1.50 |
| Silicon (Si) | ≤ 1.00 | ≤ 1.00 |
| Sulfur (S) | ≤ 0.015 | ≤ 0.015 |
| Copper (Cu) | ≤ 0.75 | ≤ 0.75 |
Note: Incoloy 800H has controlled carbon content (0.05-0.10%) for
improved creep rupture strength at high temperatures.
Mechanical Properties
| Property | Incoloy 800 (N08800) | Incoloy 800H (N08810) |
| Tensile Strength (MPa) | ≥ 520 | ≥ 450 |
| Yield Strength (MPa) | ≥ 207 | ≥ 170 |
| Elongation (%) | ≥ 30 | ≥ 30 |
Welding Considerations
Welding Methods: TIG (GTAW), MIG (GMAW), SAW.
Filler Metals: ERNiCr-3 (Inconel 82), ENiCrFe-3 (Inconel
182/Incoloy 800H compatible).
Post-Weld Heat Treatment (PWHT): Recommended for stress relief
(annealing at 1600°F / 871°C for 800H).
Applications of Incoloy 800/800H Welded Pipes
Petrochemical Industry: Heat exchanger tubes, furnace components.
Power Generation: Boiler tubes, superheater tubes.
Chemical Processing: Reactor piping, catalyst tubes.
Heat Treatment: Radiant tubes, muffles.
Nuclear Industry: Steam generator tubing.
Advantages
Over Other AlloysBetter oxidation resistance than stainless steel
(304/316) at high temperatures.
Superior creep resistance compared to Incoloy 800 due to controlled
carbon in 800H.
More cost-effective than high-nickel alloys like Inconel 600/601.
