Nickel Alloy Incoloy 800H Pipes and Tubes Standards
ASTM B407 / ASME SB407 covers seamless pipe and tube in UNS N08810. It is a seamless standard, so welded product follows ASTM B514 / ASME SB514 for pipe and ASTM B515 / ASME SB515 for tube. Seamless heat exchanger and condenser tube follows ASTM B163 / ASME SB163.
General requirements come from ASTM B829, B775 and B751. Pipe dimensions follow ASME B36.19M. Matching parts follow ASTM B564 for flanges, B366 for fittings, B409 for plate and B408 for bar.
Each lot passes a hydrostatic test or eddy current testing, plus flattening and flaring tests on tube. Because grain size is part of what makes 800H what it is, we test it and report it. Positive material identification confirms nickel and chromium on the finished length, and third-party inspection is welcome at our works.
Nickel Alloy Incoloy 800H Pipes and Tubes vs 347H and 310H: Choosing a High-Temperature Alloy
When a line runs hot, buyers weigh 800H against two stainless steels that carry "H" too.
| Point | Incoloy 800H | 347H Stainless | 310H Stainless |
|---|---|---|---|
| Nickel | 30 – 35% | 9 – 13% | 19 – 22% |
| Approx. Code Upper Limit | About 900 °C | About 815 °C | About 815 °C |
| Carburization Resistance | Good | Low | Moderate |
| Chloride Stress Corrosion Cracking | Good | Poor | Moderate |
| Relative Cost | High | Low | Medium |
Code limits vary by edition; confirm against the code for your project.
Choose 347H when the line is moderately hot, chlorides are absent and budget is tight. Choose 310H for hot, oxidizing air with light loads. Choose 800H when the line runs near or above about 600 °C under pressure, sees carburizing gas, or may meet chlorides.
Creep Strength, Heat Resistance and Corrosion Performance of Nickel Alloy Incoloy 800H Pipes and Tubes
The main job of 800H is carrying load at heat. Design codes list higher allowable stress for the H grades above about 600 °C, and plain Alloy 800 is generally limited to about 590 °C for pressure parts. With 800H, a pressure design can reach roughly 900 °C under the code, and oxidation resistance is good up to about 1100 °C where loads are light.
It also resists carburization and nitriding, which attack ordinary stainless steel in hot process gas, and it stands up to chloride stress corrosion cracking much better than 304 or 316. Resistance is not immunity, though.
Know its limits. Long exposure between about 650 and 870 °C can form carbides and sigma phase, which reduce ductility at room temperature, so plan carefully when equipment is cooled and handled after long service. Reducing sulfur atmospheres attack all nickel-iron-chromium alloys. For strong sulfuric or phosphoric acid, Incoloy 825 is a better fit.

Nickel Alloy Incoloy 800H Pipes and Tubes Mechanical and Physical Properties
| Property | Value |
|---|---|
| Tensile Strength | 450 MPa (65 ksi) min |
| Yield Strength (0.2% offset) | 170 MPa (25 ksi) min |
| Elongation | 30% min |
| Annealing Temperature | 1149 °C min |
| Grain Size | ASTM No. 5 or coarser |
| Density | approx. 7.94 g/cm³ |
| Melting Range | approx. 1357 – 1385 °C |
| Thermal Expansion (20–100 °C) | approx. 14.2 µm/m·°C |
| Thermal Conductivity (20 °C) | approx. 11.5 W/m·K |
| Magnetic Response | Essentially non-magnetic |
Room-temperature strength looks modest because the coarse grain that makes 800H creep resistant also lowers yield strength. Design from the code stress values at your operating temperature, not from these figures.
Nickel Alloy Incoloy 800H Pipes and Tubes Size and Weight Chart
Weight per metre = (OD − wall) × wall × 0.0249, with OD and wall in mm. This uses a density of 7.94 g/cm³. Treat the numbers as estimates, since wall tolerance moves the real weight.
OD and wall are in mm. Multiply the result by the pipe or tube length to obtain the total weight.
