ASTM B514 Incoloy 800/800H UNS N08800/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.
