Bilal Nickel Alloys, based in Safat, Kuwait, stands out as a top manufacturer and supplier of high-performance nickel alloy products, including Incoloy 800/800H/800HT Nuts. These nuts are crafted to offer outstanding resistance to corrosion, oxidation, and high temperatures, ensuring secure and dependable fastening in crucial industrial settings. With a focus on precision and compliance with international standards, they deliver exceptional strength, durability, and dimensional accuracy. Bilal Nickel Alloys utilizes cutting-edge production methods and rigorous quality control to produce nuts that maintain their mechanical integrity even under extreme thermal and mechanical stress, making them perfect for the chemical, petrochemical, and power generation sectors.
Incoloy 800/800H/800HT nuts are mainly made up of nickel (30–35%), iron (39.5–45%), and chromium (19–23%), with small amounts of copper and titanium added for improved stability. The H and HT versions undergo heat treatment to enhance their tensile strength, yield strength, and performance at high temperatures. These nuts boast impressive tensile strength (up to 655 MPa), excellent yield strength (275–380 MPa), and good elongation. Their strong mechanical properties help them resist thermal fatigue, stress corrosion cracking, and oxidation, ensuring reliable performance in tough, high-temperature, and corrosive industrial environments.
