Incoloy 825 Threaded Rods

Incoloy 825 Threaded Rods are long, continuously threaded bars manufactured by Zeron Fastners, designed to be cut to custom lengths for specialized bolting or anchoring applications. Fabricated from the high-nickel alloy Incoloy 825 (UNS N08825), which is alloyed with molybdenum, copper, and titanium, these rods possess exceptional properties. The material provides outstanding resistance to stress-corrosion cracking in chloride-bearing environments and excellent immunity to reducing acids like sulfuric and phosphoric acid, making them far superior to stainless steel in harsh chemical service. These rods are extensively used in various industrial sectors, including chemical processing, flue gas desulfurization systems, marine and offshore environments, and as heavy-duty anchor bolts for equipment foundations where deep, adjustable fastening is required.
