Ashraf Nickel Alloys, located in Riyadh, Saudi Arabia, is a well-respected manufacturer and supplier of **Incoloy 800/800H/800HT Nuts**. They provide top-notch fastening solutions that are specifically designed to thrive in extreme environments. These nuts are built to perform reliably in corrosive and high-temperature settings, making them perfect for critical industrial applications. With outstanding resistance to oxidation, carburization, and stress-corrosion cracking, Incoloy 800 series nuts deliver the strength and durability needed for demanding service. Ashraf Nickel Alloys offers these nuts in a variety of sizes, grades, and standards, ensuring precision, reliability, and adherence to international specifications.
The **Incoloy 800/800H/800HT Nuts** are primarily made from nickel, iron, and chromium, with carefully controlled amounts of carbon, titanium, and aluminum. The 800H and 800HT versions have a higher carbon content along with regulated levels of aluminum and titanium, which improve their creep and stress rupture properties at high temperatures. Mechanically, these nuts boast high tensile strength, toughness, and excellent metallurgical stability, maintaining their structural integrity even under prolonged exposure to heat and pressure. Their unique composition guarantees long-lasting performance in challenging operating conditions.
