ASTM B564 Inconel 825 Flanges are high-performance nickel alloy flanges manufactured from UNS N08825 (Incoloy 825), known for exceptional resistance to corrosion, oxidation, and stress corrosion cracking. These flanges are widely used in chemical processing, oil & gas, marine, and power industries due to their durability in extreme environments. Available in types such as Blind, Weld Neck (WNRF), Socket Weld, and Slip-On, they comply with ANSI B16.5 standards for reliable performance.
What are ASTM B564 Inconel 825 Flanges?
ASTM B564 Inconel 825 Flanges are forged flanges made from Nickel-Iron-Chromium Alloy 825 (UNS N08825). This alloy contains molybdenum, copper, and titanium, offering superior resistance to pitting, crevice corrosion, and acidic environments.
We manufacture and supply a wide range of ASTM B564 UNS N08825 Flanges, engineered to perform in harsh industrial applications where conventional materials fail. These Incoloy 825 Flanges provide long-term reliability, especially in environments exposed to sulfuric and phosphoric acids.
