Inconel 686 Special Alloy UNS N06686 Overlay Of Ferrous Components For Marine Service
Product 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.

Feature
INCONEL alloy 686 exhibits excellent resistance to general, galvanic, and localized corrosion and hydrogen embrittlement in seawater.In addition, seawater has only a minor effect on the fatigue strength of the alloy. Thus, alloy 686 is an ideal material for marine service.

APPLICATIONS
Alloy 686 fasteners (bolts, nuts, studs, etc.) perform well in marine service. Alloy 686 can be strengthened by cold working to yield strength levels of 150 ksi if high strength bolting is required. These high strength fasteners offer essentially the same resistance to corrosion in seawater as annealed material.
INCONEL alloy 686 welding products (INCO-WELD 686CPT) are ideal for overlay of ferrous components for marine service. With their high alloy content and low iron content, overlays deposited with alloy 686 welding products offer excellent corrosion resistance. It is often possible to use thinner overlay deposited with fewer weld layers when using alloy 686 products as compared
