The primary advantage of using Incoloy 800 flanges lies in their ability to retain structural integrity under prolonged exposure to elevated temperatures. This makes them suitable for use in heat exchangers, process piping, pressure vessels, furnace components, and superheaters. The combination of nickel and chromium in UNS N08800 provides excellent corrosion resistance in aqueous and high-temperature atmospheres, while the iron content contributes to their strength and stability. Adinox Overseas ensures that each flange is precision-engineered, rigorously tested, and certified with material test reports to meet global industry standards.
