Shanghai Hangbo Alloy Group Co., Ltd. is an ISO 9001:2015 certified manufacturer and global supplier of Inconel 601 (UNS N06601), providing precision-quality round bars, seamless tubes, and plates for high-temperature furnace, petrochemical, and aerospace applications.
Quick Answer: What Is Inconel 601?
Inconel 601 (UNS N06601, W.Nr. 2.4851) is a nickel-chromium alloy with a deliberate addition of approximately 1.4% aluminum. This aluminum forms a tightly adherent, protective Al₂O₃ (alumina) oxide scale on the surface, giving the alloy exceptional resistance to oxidation, carburization, and spalling under cyclic thermal loading up to 1200°C (2200°F). Combined with high mechanical strength and good ductility, it is the preferred alloy for thermal processing equipment and industrial furnace components.
Key standards: ASTM B166 (bar/rod), ASTM B167 (tube), ASTM B168 (plate/sheet), AMS 5715 (bar), AMS 5540B

Frequently Asked Questions (FAQ)
Why is Inconel 601 better than Inconel 600 for high-temperature oxidizing environments?
The ~1.4% aluminum addition in Inconel 601 enables the formation of a protective Al₂O₃ scale that is far more stable and adherent at high temperatures than the Cr₂O₃ scale formed on Inconel 600. This results in significantly lower metal loss rates above 1000°C and superior resistance to thermal cycling.
Can Inconel 601 be used in carburizing atmospheres?
Yes. Inconel 601 offers good resistance to carburization — the carbon uptake that can embrittle steel alloys in high-temperature furnace atmospheres. This makes it a preferred material for heat-treat baskets, fixtures, and furnace rolls.
Is Inconel 601 weldable?
Yes. Inconel 601 can be welded by GTAW (TIG), GMAW (MIG), and SMAW processes. The recommended filler is Inconel Filler Metal 601 (ERNiCrFe-11) for matching composition, or FM 82 for general-purpose work. No pre-heating is required.
What sizes does Shanghai Hangbo Alloy Group stock?
We maintain stock of commonly used diameters (6–250 mm round bars), standard tube ODs (6–114 mm), and sheet/plate thicknesses (0.5–50 mm). Custom sizes are manufactured to order. Contact us for a real-time stock list.
