Incoloy 825 Anchor Fasteners

Incoloy 825 Anchor Fasteners, including anchor bolts and various anchor types (wedge, sleeve), are heavy-duty fastening solutions manufactured by Zeron Fastners. They are specifically engineered to secure structural elements and machinery to concrete foundations, particularly in areas subject to aggressive chemical attacks or marine exposure. Composed of Incoloy 825 (UNS N08825), this alloy leverages a blend of nickel, iron, chromium, molybdenum, copper, and titanium to deliver superior protection against stress-corrosion cracking and a broad spectrum of chemicals, notably reducing acids like sulfuric and phosphoric acid. The use of Incoloy 825 ensures the long-term structural integrity of equipment in chemical plants, oil and gas platforms, and pollution control facilities where standard carbon or stainless steel anchors would rapidly fail due to corrosion.
