Inconel 686 Chemical Composition
Inconel 686 Material Properties Overview
As a leading supplier & manufacturer in China, Arialloy supply cost-effective Inconel 686 Products.
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.
Its matched composition welding products, designated as INCO-WELD® filler metals and welding electrode 686 CPT® also offer exceptional as-welded resistance to sulfuric or hydrochloric acids, to mixtures of the two, and to crevice or pitting corrosion in hot concentrated acid chloride solutions. These welding products are also used for dissimilar and overmatched welding applications.
Inconel alloy 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 alloy 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.
It offers resistance to both reducing and oxidizing acids and to mixed acid solutions. It 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 Mechanical Properties
In the annealed condition, the alloy exhibits moderate yield strengths of 25,000 to 50,000 psi (172 to 345 MPa). Yield strengths in that range, combined with elongations of 55 to 35%, permit the alloy to be fabricated with little difficulty. Heavily coldworked material, however, can have tensile strengths as high as 220,000 psi (1517 MPa).
Values for properties reported in this publication are typical but are not suitable for specification purposes unless stated as minimum or maximum.
Inconel 686 Temperature Characteristics
The combination of high strength and oxidation resistance at temperatures over 1800°F (980°C) makes INCONEL alloy 617 an attractive material for such components as ducting, combustion cans, and transition liners in both aircraft and land-based gas turbines. Because of its resistance to high-temperature corrosion, the alloy is used for catalyst-grid supports in the production of nitric acid, for heat-treating baskets, and for reduction boats in the refining of molybdenum. INCONEL alloy 617 also offers attractive properties for components of power-generating plants, both fossilfueled and nuclear.
