Inconel® Alloy 601 (UNS N06601) Ni 61, Fe Bal, Cr 22, Al 1.4
Nickel, higher chromium content for better resistance to oxidizing and reducing environments; for severely corrosive environments at elevated temperatures. Good oxidation resistance to 2200 ºF. Good formability.
Instrument probes, furnace muffles, electronic components, chemical and food process equipment, heat treating equipment, nuclear steam generator tubing.
Inconel nickel-chromium-iron alloy 601 is a general-purpose engineering material for applications that require resistance to heat and corrosion. The outstanding characteristic of Inconel alloy 601 is its resistance to high-temperature oxidation. The alloy also has good resistance to aqueous corrosion, has high mechanical strength, and is readily formed, machined, and welded.

| Additional Information |
The limiting chemical composition of Inconel alloy 601 is listed in table 1. The composition is a face-centered-cubic solid solution with a high degree of metallurgical stability. The alloy's nickel base, in conjunction with substantial chromium content, provides resistance too many corrosive media and high-temperature environments. Oxidation resistance is further enhanced by the aluminum content. Gas turbine engine components: combustion chambers, and afterburners. Other uses also include: high temperature ball bearing service, springs, and heart valves. Alloy L-605 is the strongest of the formable cobalt alloys, useful for continuous service to 1800 ºF. Because of long and widespread use, this alloy has been the subject of many investigations to determine its properties over a wide range of conditions, thus making it an unusually well characterized material. Alloy L-605 is also known as alloy 25. When exposed for prolonged periods at intermediate temperatures, alloy L-605 exhibits a loss of room temperature ductility in much the same fashion as other super alloys, such as X or 625. Alloy L-605 is welded using gas tungsten arc, gas metal arc, shielded metal arc, electron beam and resistance welding. Submerged arc welding is not recommended. Use good joint fit-up, minimum restraint, low inter-pass temperature and cool rapidly from welding. For maximum ductility fabricated components should be annealed 2150 - 2250 ºF, rapid cool. Corrosion Resistance Resistance to high temperature oxidation and carburization is good. The alloy, while not primarily intended for aqueous corrosion, is also resistant to corrosion by acids such as hydrochloric and nitric acid, as well as being resistant to wet chlorine solutions. |
