Special Metals INCONEL® Alloy 686 Nickel Superalloy Rod (UNS N06686)
Categories: Metal; Nonferrous Metal; Nickel Alloy; Superalloy
Material Notes: 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 alloy 686 is protected by U.S. patent 5,019,184.

Tensile strength (ultimate and yield) and elongation values reported here are typical for rod. Other property values are typical of INCONEL® alloy 686.
