Inconel 617 – High-Performance Nickel-Chromium-Cobalt-Molybdenum Alloy
Supplied by Huaxiao-Alloy – Your Trusted Global Alloy Partner
Introduction to Inconel 617
Inconel 617 is a solid-solution strengthened nickel-chromium-cobalt-molybdenum alloy designed for exceptional strength, oxidation resistance, and stability at elevated temperatures. This high-performance alloy is widely recognized for its ability to withstand temperatures above 1000°C (1832°F), making it a preferred material in industries where creep resistance, oxidation control, and mechanical stability are critical.
At Huaxiao-Alloy, we supply Inconel 617 plates, sheets, bars, pipes, tubes, and customized components, delivering solutions that meet the most demanding requirements of aerospace, power generation, petrochemical, and gas processing industries.
1. Key Properties of Inconel 617
Inconel 617 achieves its remarkable performance through its unique chemical composition:
Nickel (Ni): Base element, provides corrosion resistance and high-temperature strength.
Chromium (Cr ~22%): Delivers outstanding oxidation and scaling resistance.
Cobalt (Co ~12%): Enhances strength and thermal stability.
Molybdenum (Mo ~9%): Increases creep resistance and tensile strength.
Performance Highlights
High-Temperature Strength: Retains mechanical stability above 1000°C.
Excellent Oxidation Resistance: Protective oxide film forms even under severe oxidizing conditions.
Good Fabricability: Can be welded and formed using conventional methods.
Creep & Fatigue Resistance: Ensures reliability in long-term, high-stress applications.
Corrosion Resistance: Withstands aggressive chemical environments including carburization and chlorination.
2. Typical Applications of Inconel 617
Huaxiao-Alloy provides Inconel 617 products for multiple mission-critical sectors:

3. Mechanical Properties of Inconel 617
| Property | Typical Value at Room Temp | High-Temp (800°C) |
|---|---|---|
| Tensile Strength | 850 MPa (123 ksi) | 460 MPa (67 ksi) |
| Yield Strength (0.2% PS) | 440 MPa (64 ksi) | 280 MPa (41 ksi) |
| Elongation | 40% | 25% |
| Hardness (Rockwell B) | 95 | – |
These values illustrate Inconel 617’s superior strength retention even under extreme heat.
4. Heat Resistance & Oxidation Behavior
One of the defining characteristics of Inconel 617 is its ability to resist scaling and oxidation in air at temperatures exceeding 1100°C. Unlike many alloys, it maintains dimensional stability while resisting grain coarsening, making it ideal for long-term use in thermal cycling environments.
5. Corrosion Resistance
Inconel 617 shows excellent resistance to:
Hot oxidizing environments (furnaces, turbines).
Carburization and nitridation in petrochemical processing.
Halide and chloride attack in high-temperature gases.
This makes it particularly valuable in industrial gas processes, nuclear reactors, and chemical plants.
6. Standards & Equivalent Grades
Inconel 617 conforms to multiple international standards:
UNS: N06617
Werkstoff Nr.: 2.4663
ASTM: B166, B167, B168, B564
AMS: 5887, 5888, 5889
Huaxiao-Alloy supplies material fully certified under these specifications, ensuring global quality compliance.
