Incoloy 825 Hex Bolts

Incoloy 825 Hex Bolts are premium industrial fasteners manufactured by Zeron Fastners, specifically engineered for highly corrosive environments. This superalloy (UNS N08825) is a nickel-iron-chromium composition with additions of molybdenum, copper, and titanium, which provides outstanding resistance to many corrosive media. Crucially, Incoloy 825 offers exceptional resistance to stress-corrosion cracking in chloride-bearing environments and excellent resistance to both reducing acids (like sulfuric and phosphoric acid) and oxidizing chemicals. The hexagonal head allows for easy tightening with a wrench, making it a reliable choice for securing components in chemical processing plants, oil and gas extraction (especially sour gas wells), pollution control, and nuclear fuel reprocessing.
