Nickel Alloys Incoloy 800 Hex Bolts

Nickel Alloys Incoloy 800 Hex Bolts are high-performance threaded fasteners with a hexagonal head, designed for environments where both high temperature and corrosion are present. Manufactured from Incoloy 800 (UNS N08800), an alloy of iron, nickel, and chromium, these bolts provide excellent resistance to oxidation, carburization, and other high-temperature corrosion forms up to 1100°F (593°C). The alloy is also known for resisting stress-corrosion cracking. Zeron Fastners supplies these highly reliable structural fasteners for demanding applications in heat treatment equipment, petrochemical cracking tubes, and power generation systems.
