Inconel 617 Tube Supplier, Stockist and Exporter
Table of Contents
Aurico Alloys LLP supplies Inconel 617 tube (N06617, Werkstoff 2.4663) to ASTM B167 from Mumbai, to customers across India and in more than 40 export markets.
Inconel 617 tube is bought for pressure at temperature. Its 10–15% cobalt and 8–10% molybdenum give it the creep-rupture strength to hold a pressurised tube wall between 800 and 1100°C, which is why it is the tube in advanced ultra-supercritical boiler superheaters and in the heat exchangers of high-temperature gas-cooled reactor designs – places where a thinner wall in a stronger alloy is the only way the numbers close.

Mechanical and Physical Properties
Room-temperature tensile strength is around 740 MPa, but a 617 tube is sized on creep-rupture strength, not on that figure. Between 800 and 1100°C it keeps the highest creep-rupture strength of the solid-solution nickel alloys, with good resistance to the carburising and oxidising gas on the fire side.
Industry Applications
Why Inconel 617 tube
A tube that carries pressure above 800°C fails by creep, so the alloy that allows the thinnest wall at the design life wins – and in the 1000–1100°C range that is 617. If the tube only has to survive the atmosphere without carrying much load, 601 tube resists oxidation as well for less money. Order seamless tube to ASTM B167; the B546 number also printed for this grade is a welded pipe standard for 3 in. and larger, and does not cover tube.
| Industry | Typical use |
|---|---|
| Power generation | Superheater and reheater tube for advanced ultra-supercritical boilers. |
| Nuclear | Heat-exchanger tube in high-temperature gas-cooled reactor designs. |
| Petrochemical | High-temperature process heater and reactor tube where creep governs the wall. |
| Heat treatment | Load-bearing furnace tube working above 1000°C. |
Testing and Certification
Tube ships with an EN 10204 3.1 mill test certificate stating heat number, chemical analysis and mechanical properties. For pressure duty we add hydrostatic and ultrasonic testing and positive material identification on request, and third-party release by Lloyd’s Register, Bureau Veritas, SGS or TÜV can be arranged under our ISO 9001:2015 system. Tell us the design code at enquiry, since boiler work usually carries its own inspection requirements.
