Nickel-Alloy 800H Fasteners are molybdenum-bearing austenitic alloys which are more resistant to general corrosion and pitting crevice corrosion than the conventional chromium nickel austenitic steel. The high carbon version of Nickel-Alloy 800HT Fasteners shows improved corrosion resistance due to a minimized carbide precipitation during welding.

FAQs – Incoloy 800 / 800H / 800HT Fasteners

Incoloy 800, 800H, and 800HT fasteners are high-performance fastening components made from nickel-iron-chromium alloys (UNS N08800, N08810, N08811). These alloys are designed to provide excellent strength and stability in high-temperature and corrosive environments.

The main difference lies in carbon and alloying elements. Incoloy 800 is the base grade, while 800H has higher carbon content for improved creep resistance, and 800HT includes controlled aluminum and titanium for enhanced high-temperature strength and stability.

These fasteners offer excellent resistance to oxidation, carburization, and high-temperature corrosion. They maintain structural stability at elevated temperatures and provide high creep rupture strength along with resistance to stress corrosion cracking.

They are widely used in petrochemical processing, heat treatment equipment, power plants, nuclear industries, and chemical processing systems. Common applications include heat exchangers, furnace components, and high-temperature piping systems.

Incoloy 800/800HT fasteners are available in various forms such as bolts, nuts, screws, washers, studs, threaded rods, and custom fasteners. They are manufactured in different sizes and standards including ASTM, DIN, and ISO.
