Inconel 601 seamless pipe is a high-temperature nickel-chromium alloy pipe designed for applications requiring excellent oxidation resistance, carburization resistance, and mechanical strength at elevated temperatures.
The alloy is widely used in heat treatment, petrochemical processing, power generation, and industrial furnace systems where conventional stainless steels cannot withstand prolonged exposure to extreme temperatures.
Werkstoffbezeichnungen
| Standard | UNS | W.Nr. | ASTM Pipe Standard | Legierungsname |
| Bezeichnung | N06601 | 2.4851 | ASTM B167 | Inconel 601 |
Chemische Zusammensetzung
Typical composition:
| Element | Inhalt (%) |
| Nickel (Ni) | 58.0 – 63.0 |
| Chrom (Cr) | 21.0 – 25.0 |
| Eisen (Fe) | Gleichgewicht |
| Aluminium (Al) | 1.0 – 1.7 |
| Kohlenstoff (C) | Max 0.10 |
| Mangan (Mn) | Max 1.0 |
| Silizium (Si) | Max 0.5 |
The addition of aluminum together with chromium forms a dense oxide layer that protects the alloy from high-temperature oxidation.
Mechanische Eigenschaften
Typical room-temperature properties:
| Eigentum | Wert |
| Zugfestigkeit | ≥ 550 MPa |
| Streckgrenze | ≥ 205 MPa |
| Verlängerung | ≥ 30% |
| Dichte | 8.11 g/cm³ |
| Schmelzbereich | 1360–1411°C |
Key Performance Characteristics
1. Outstanding Oxidation Resistance
Inconel 601 develops a tightly adherent oxide scale that protects the surface at temperatures up to approximately 1200°C.
This makes it suitable for continuous exposure to hot combustion gases.
2. Excellent Carburization Resistance
Many furnace atmospheres contain carbon-rich gases that attack conventional alloys.
Inconel 601 maintains structural integrity even under severe carburizing conditions.
3. High-Temperature Strength
The alloy retains useful mechanical strength at temperatures where carbon steel and many stainless steels begin to lose load-bearing capability.
4. Sulfidation Resistance
Performs well in sulfur-containing atmospheres commonly found in refining and thermal processing industries.
5. Good Fabricability
Can be welded, formed, and machined using conventional methods for nickel alloys.

Typical Application
Ethylene Cracking Furnace Radiant Coil
One of the most common uses of Inconel 601 seamless pipe is in ethylene steam cracking furnaces.
Operating Conditions
- Temperature: 950–1100°C
- Continuous thermal cycling
- Carbon-rich atmosphere
- Oxidizing combustion gases
Why Inconel 601?
Austenitic stainless steels often suffer from:
- Oxidation scaling
- Carburization
- Premature tube failure
Inconel 601 provides:
- Longer service life
- Better oxidation protection
- Reduced shutdown frequency
- Improved process reliability
As a result, many petrochemical plants use Inconel 601 tubes and pipes for critical high-temperature furnace sections.
