Often used in chemical processing, nuclear engineering and the aerospace industry, inconel 600 is a non-magnetic and highly resistant to corrosion and oxidation. It is composed of nickel, chromium and iron.
The chromium content in inconel 600 gives it superior resistance to a wide range of corrosives, and even greater resistance than commercially pure nickel in many conditions. It has fair resistance to strongly acidic solutions, but can withstand temperatures up to 2000degF (1093degC).
In addition to high corrosion resistance, this alloy is also extremely durable. It has good strength and ductility at elevated temperatures, making it ideal for heat treating equipment. In chemical processing, it can be used in heaters, stills and bubble towers for producing fatty acids, as well as process equipment for handling sodium sulfide. It can also be found in furnace components for petrochemical operations and equipment that handles abietic acid for pulp and paper production.
This material has a combination of excellent mechanical properties and cold forming characteristics similar to those of chromium-nickel stainless steels. It is not susceptible to stress corrosion cracking in most environments, but it is sensitive to caustic alkalies and should be stressed relieved prior to use in these applications. This alloy is also not easily attacked by wet chlorine gas and is nearly immune to chloride-induced stress corrosion cracking. It is also not affected by aging due to crevice formation, making it an ideal choice for most environments. American Elements produces inconel 600 in a variety of forms including bar, wire cuts, sheet, plate, strip and tubing.
