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.
