Inconel 601 Pipes Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies inconel 601 pipes (N06601, Werkstoff 2.4851) from ready stock in Mumbai, to customers across India and in more than 40 export markets.
Pipe is specified by nominal bore and schedule, and is the backbone of any process line carrying corrosive or high-temperature fluid where wall thickness has to be matched to design pressure and corrosion allowance.
Inconel 601 holds an aluminium-stabilised oxide film that survives repeated thermal cycling, so it outlasts alloy 600 wherever the process heats and cools.

Identifiers and physical constants for Inconel 601. A dash means no such designation is published for this grade.
Chemical Composition
Nickel 58-63% with 21-25% chromium, 1.0-1.7% aluminium and the balance iron. The aluminium forms a tightly adherent oxide that resists spalling under thermal cycling.
| Element | Min (%) | Max (%) |
|---|---|---|
| Nickel (Ni) | 58.0 | 63.0 |
| Chromium (Cr) | 21.0 | 25.0 |
| Iron (Fe) | — | Balance |
| Aluminium (Al) | 1.0 | 1.7 |
| Carbon (C) | — | 0.10 |
| Manganese (Mn) | — | 1.0 |
| Sulfur (S) | — | 0.015 |
| Silicon (Si) | — | 0.50 |
| Copper (Cu) | — | 1.0 |
Composition limits for Inconel 601. 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
Annealed tensile strength around 550-760 MPa. Outstanding oxidation resistance to 1200°C and good strength under cyclic heating.
Industry Applications
Why this grade
Inconel 601 adds over 1% aluminium to the 600 chemistry, so it forms a tight alumina scale and resists oxidation to around 1200°C. It is the grade to specify when the part faces radiant heat rather than load: above 1000°C its creep strength falls well short of 617, so a furnace is often built with 617 in the load-bearing frame and 601 as the skin facing the heat.
| Industry | Typical use |
|---|---|
| Heat treatment | Radiant tubes, muffles, retorts and furnace baskets. |
| Petrochemical | Catalyst regenerators, flare tips and thermal reactors. |
| Power generation | Combustion hardware and waste-to-energy plant. |
| Chemical processing | Insulating cans and high-temperature process equipment. |
| Industrial heating | Burner nozzles, tube hangers and grate bars. |
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.
