Inconel 686 (UNS N06686) Fin Folded Sheet High-Corrosion-Resistance Nickel Alloy for Heat Exchanger Applications

Product Description INCONEL 686 (UNS N06686) Fin Folded Sheet is a premium nickel-based alloy fin material specifically designed for extremely aggressive corrosive environments combined with heat-transfer requirements. Thanks to its very high molybdenum and tungsten content, Alloy 686 provides outstanding resistance to pitting, crevice corrosion, stress corrosion cracking (SCC), as well as mixed acids, wet chlorine, and seawater. Manufactured into precision fin folded sheets, INCONEL 686 is widely used in heat exchangers, condensers, coolers, and pollution control systems, especially where conventional nickel alloys such as C-276 or C-22 may reach their performance limits. All fin folded sheets are supplied in annealed condition, with controlled thickness, uniform fin geometry, and full Mill Test Certificate (EN 10204 3.1).
