Inconel 686 Description
INCONEL alloy 686 (UNS N06686 / W.Nr. 2.4606) 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.
Inconel 686 Corrosion Resistance
INCONEL 686 offers outstanding resistance to general corrosion, to stress-corrosion cracking, and to pitting and crevice corrosion. Its resistance to intergranular precipitation during welding maintains its corrosion-resistance in the heat-affect zones of welded joints.
INCONEL 686 offers resistance to both reducing and oxidizing acids and to mixed acid solutions. INCONEL alloy 686 is especially suited to handling mixed acids containing high concentrations of halides. It has shown good resistance to mixed acid media with pH levels of 1 or less, and chloride levels of over 100,000 ppm.
Inconel 686 Characteristics
Excellent resistance to chloride pitting and crevice corrosion cracking
Immune to Chloride ion stress corrosion Maintains
high strength at elevated temperatures
Resistant to sea water, in both flowing and stagnant condition
Heat resistant
