Chemical Composition of Inconel 601 Pipe, wt.%
| Ni | Cr | Al | Fe | Mn | Si | C | S | Cu |
|---|---|---|---|---|---|---|---|---|
| 58.0 – 63.0 | 21.0 – 25.0 | 1.0 – 1.7 | Balance | ≤ 1.50 | ≤ 0.50 | ≤ 0.10 | ≤ 0.015 | ≤ 1.00 |
Why is The Aluminum Content So Important?
- Synergistic Effect:
Aluminum interacts with high chromium content to form an extremely stable aluminum oxide/chromium oxide film on the pipe surface,thereby protecting itself. - Anti-Spalling Properties:
This film exhibits exceptional adhesion under extreme thermal cycling conditions (repeated heating and cooling),preventing thinning and damage to the metal surface caused by spalling.
Comparison with Inconel 600
Mechanical Properties of UNS N06601
| Tensile Strength | Yield Strength (0.2% Offset) | Elongation | Hardness (Max) |
|---|---|---|---|
| ≥ 550 MPa(80,000 psi) | ≥ 205 MPa(30,000 psi) | ≥ 30% | 120 – 200 HB |
The true advantage of UNS N06601 lies in its stability at elevated temperatures. As temperatures rise, its strength decreases at a relatively slow rate.
At 650°C (1200°F), tensile strength remains around 400 MPa.
Under long-term loading at temperatures above 815°C (1500°F), Alloy 601 exhibits superior creep resistance compared to Alloy 600, owing to its stable aluminum-chromium oxide protective layer.

Common Questions About Inconel 601 Pipe
Yes.It exhibits excellent weldability,with commonly used methods including GTAW (TIG) and GMAW (MIG).It is recommended to use Inconel 601 filler wire or Alloy 182 welding rod to ensure the weld’s oxidation resistance matches that of the base material.
Because it possesses outstanding resistance to carburization.In carburizing furnaces,nitriding equipment,and carbonitriding environments,601 effectively blocks the penetration of carbon atoms,preventing material embrittlement.
Generally.While it exhibits excellent oxidation resistance,its performance is weaker in highly reducing sulfidic environments.If significant sulfur is present in the environment,we recommend consulting our experts for evaluation or selecting an alloy with a higher silicon content.
No.Inconel 601 is non-magnetic at room temperature.
Yes.Inconel 601 maintains excellent impact toughness across an extremely wide temperature range,from cryogenic to ultra-high temperatures.
