Inconel 686 Outstanding Corrosion-resistance in a Range of Severe Environments
INCONEL 686 is a single-phase, austenitic Ni-Cr-Mo-W alloy offering
outstanding corrosion-resistance in a range of severe environments.
Its high nickel (Ni) and molybdenum (Mo) provide good
resistance in reducing conditions, and high chromium (Cr) offers
resistance to oxidizing media. Molybdenum (Mo) and tungsten
(W) aid resistance to localized corrosion such as pitting.
Iron(Fe) is closely controlled to enhance properties. Low
carbon (C) helps minimize grain boundary precipitation to
maintain corrosion-resistance in the heat-affected
zones of welded joints. Resistance to general, pitting and
crevice corrosion increases with the alloying
(Cr+Mo+W) content, and INCONEL alloy 686 scores higher than
competitive materials.
Inconel 686 is used for resistance to aggressive media in
chemical processing, pollution
control, pulp and paper manufacture, and waste management
applications.
