Inconel 617 Fittings Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies inconel 617 fittings (N06617, Werkstoff 2.4663) from ready stock in Mumbai, to customers across India and in more than 40 export markets.
Fittings carry the same corrosion duty as the pipe they join but see higher stress concentration at every change of direction, so grade traceability and wall thickness at the extrados matter more here than anywhere else in a piping system.
Inconel 617 holds creep strength at the temperatures where gas turbines and advanced ultra-supercritical boilers actually run.

Identifiers and physical constants for Inconel 617. A dash means no such designation is published for this grade.
Chemical Composition
Nickel balance with 20-24% chromium, 10-15% cobalt, 8-10% molybdenum and 0.8-1.5% aluminium. Cobalt and molybdenum provide solid-solution strengthening; aluminium supports the oxide.

Composition limits for Inconel 617. These are specification limits for the grade, not measured values for a lot; the mill test certificate supplied with your order states the actual analysis.
Mechanical and Physical Properties
Room-temperature tensile strength around 740 MPa, with exceptional creep-rupture strength between 800°C and 1100°C and good resistance to carburising and oxidising atmospheres.
Industry Applications
Why this grade
Inconel 617 carries 8-10% molybdenum alongside cobalt, and delivers the highest creep-rupture strength of the solid-solution nickel alloys in the 1000-1100°C range. Choose it over 601 when the component has to hold load at temperature rather than merely survive the atmosphere; choose 601 over it when oxidation resistance matters more than retained strength.
| Industry | Typical use |
|---|---|
| Power generation | Advanced ultra-supercritical boiler tubing and headers. |
| Aerospace | Combustion cans, transition liners and ducting. |
| Petrochemical | Catalytic reformer and high-temperature reactor internals. |
| Heat treatment | Furnace components under sustained load. |
| Nuclear | High-temperature gas-cooled reactor hardware. |
Testing and Certification
Every consignment ships with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. Depending on the specification we can add positive material identification, ultrasonic and dye-penetrant testing, intergranular corrosion testing to ASTM G28 or A262, hydrostatic testing, and third-party inspection release from Lloyd's Register, Bureau Veritas, SGS or TUV.
Aurico Alloys LLP operates an ISO 9001:2015 quality management system, and can certify material to NACE MR0175 / ISO 15156 for sour service where the grade permits.
