INCONEL® (nickel-chromium-iron) alloy 600 (UNS N06600/W.Nr. 2.4816) is a standard engineering material for applications which require resistance to corrosion and heat. The alloy also has excellent mechanical properties and presents the desirable combination of high strength and good workability.

Applications

The alloy is a standard material of construction for nuclear reactors. It has excellent resistance to corrosion by high-purity water, and no indication of chloride-ion stress-corrosion cracking in reactor water systems has been detected. For nuclear applications, the alloy is produced to exacting specifications and is designated INCONEL alloy 600T.

Typical applications are:

• Thermocouple sheathing in aggresive atmospheres.
• Vinylchloride monomer production: resistance to chlorine, hydrogen chloride, oxidation and carburization.
• Conversion of uranium oxide to hexafluoride: resistance to attack by hydrogen fluoride.
• Production and use of caustic alkalis, particularly in the presence of sulphur compounds.
