About the alloy
Built to resist heat and scaling
HAGUE FASTENERS makes Inconel 601 fasteners in the UK for furnaces, heat treatment equipment and other high temperature plant. Alloy 601 is a nickel-chromium alloy with an addition of aluminium, which gives it outstanding resistance to oxidation and other forms of high temperature corrosion.
The aluminium helps the alloy form a tightly adherent oxide scale that resists spalling under thermal cycling, and it keeps good mechanical properties at elevated temperature. For fasteners it is chosen where the main threat is scaling and hot corrosion. See all Inconel alloys.

Questions
Frequently asked questions
What is the difference between Inconel 600 and Inconel 601?
Inconel 601 has more chromium and an addition of aluminium, so it resists oxidation at high temperature better than Inconel 600. Inconel 600 has a higher nickel content.
Where are Inconel 601 fasteners used?
Inconel 601 fasteners are used in furnaces, heat treatment equipment, petrochemical plant and gas turbines, where oxidation and scaling at high temperature are the main concern.
What is the equivalent of Inconel 601?
Inconel 601 is also known as UNS N06601 and Werkstoff Nr. 2.4851, and is covered by ASTM B166, B167 and B168.
Can you make Inconel 601 parts as one-offs?
Yes. We make Inconel 601 parts from a single prototype or breakdown replacement to batches of several hundred.
