An Inconel 825 flange is a bolted piping connection component made from Alloy 825 (also called Incoloy 825 / UNS N08825 / Werkstoff 2.4858)—a nickel-iron-chromium alloy with molybdenum, copper and titanium. Buyers select Alloy 825 flanges where the alloy’s corrosion resistance and the project’s mechanical or service requirements are relevant; suitability still depends on the actual medium, temperature and design documents. For nickel-alloy forgings, ASTM B564 commonly covers UNS N08825 (ASME SB-564 when code-required). Flange dimensions, class and pressure-temperature ratings are specified separately under the applicable ASME B16 standard (typically B16.5 within its NPS scope; B16.47 only where large-diameter practice applies).
