Incoloy 800H/800HT Nuts - FAQs

Incoloy 800H/800HT is a nickel-iron-chromium alloy renowned for its high temperature and corrosion resistance. These alloys are often used in applications where exposure to elevated temperatures and aggressive environments is common.

Incoloy 800H has a controlled carbon content optimized for high-temperature strength, while 800HT offers superior creep and stress rupture properties due to its higher creep-rupture strength. The choice between them depends on the specific application requirements.

Incoloy 800H/800HT Nuts offer exceptional resistance to oxidation, carburization, and nitridation in high-temperature settings. They maintain their mechanical properties and structural integrity even in extreme environments.

These nuts find applications in industries such as petrochemical, chemical processing, power generation, and heat-treating, where elevated temperatures and corrosive atmospheres are prevalent.

Yes, these nuts demonstrate good corrosion resistance in aqueous environments, especially in conditions with sulfur-containing atmospheres. However, their corrosion resistance might differ based on factors like temperature and concentration.

Incoloy 800H can handle temperatures up to 1100°C (2010°F), while 800HT offers even better performance up to 1150°C (2100°F), making them ideal for high-temperature applications.

Incoloy 800H/800HT Nuts play a vital role in improving energy efficiency in industries like power generation by withstanding high temperatures and maintaining structural integrity, reducing downtime and the need for frequent replacements.

Absolutely, the exceptional heat resistance and corrosion resistance of these alloys make them candidates for use in advanced nuclear reactors, contributing to safer and more efficient nuclear energy generation.

Beyond industrial use, these alloys can be creatively incorporated into sculptures and architectural elements exposed to extreme outdoor conditions, thanks to their longevity and corrosion resistance.
