Brand Name
INCONEL® 686
Trade NameAlloy 686
DescriptionAlloy 686 / 2.4606 is a nickel-chromium-molybdenum-tungsten alloy.
Special PropertiesOutstanding corrosion resistance in reducing environments. Good resistance to oxidizing media. Molybdenum and Tungsten increase the resistance to localized corrosion such as pitting.
ApplicationChemical processing, pulp and paper industry, treatment of wastes.
