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.
