Choosing the right nickel alloy tube
This list is organised by what the tube is actually built for — a heat exchanger and steam-generator perspective, not just the alloy family.
| Alloy | UNS | Seamless Spec | Pick it when |
|---|---|---|---|
| Nickel 201 | N02201 | B163 | Caustic evaporator tube above 315°C. Low carbon avoids graphitisation at temperature. |
| Inconel 600 | N06600 | B166 | Nuclear steam generator tube, or any exchanger where chloride stress corrosion cracking rules out stainless. |
| Inconel 601 | N06601 | B167 | Furnace-mounted heat exchanger tube running above 1150°C. |
| Inconel 625 | N06625 | B444 | Offshore heat exchanger and umbilical tube where high strength and corrosion resistance are both needed. |
| Incoloy 800H / 800HT | N08810 / N08811 | B163 | Reformer and pyrolysis furnace tube running sustained above 600°C. |
| Incoloy 825 | N08825 | B423 | Sulphuric acid cooler tube, sour gas heat exchangers. |
| Monel 400 | N04400 | B165 | Seawater condenser tube, particularly where hydrofluoric acid may be present in the process stream. |
| Hastelloy C276 | N10276 | B622 | Heat exchanger tube in a mixed acid stream where you are not certain of the exact fluid composition. |
| Hastelloy B2 | N10665 | B622 | Pure hydrochloric acid heat exchanger tube in reducing conditions only. |
| Alloy 20 | N08020 | B729 | Sulphuric acid process tube across a range of concentrations and temperatures. |
If your service condition is milder than these — general cooling water, moderate chlorides — a
316L or 254 SMO tube
will do the job at a fraction of the cost.
Sizes and wall thicknesses
Nickel alloy tube follows the same OD and BWG dimensional system as stainless tube. Density varies significantly by alloy, so use the correct value below rather than a single blanket constant.
| Alloy | Density (g/cm³) |
|---|---|
| Nickel 200 / 201 | 8.90 |
| Inconel 600 | 8.47 |
| Inconel 625 | 8.44 |
| Incoloy 800 / 800H / 800HT | 7.94 |
| Incoloy 825 | 8.14 |
| Monel 400 | 8.80 |
| Hastelloy C276 | 8.89 |
| Alloy 20 | 8.08 |
Weight formula: kg per metre = (OD minus WT) x WT x density x 0.00000785, both dimensions in mm.
