Incoloy 800/800H/800HT nuts are crafted from iron-nickel-chromium alloys known for exceptional strength and oxidation resistance at high temperatures. Their chemical composition typically includes nickel (30–35%), chromium (19–23%), and controlled carbon levels, with additions of aluminum and titanium for enhanced stability. These grades offer excellent mechanical properties such as high tensile strength, superior creep resistance, and reliable performance under thermal stress. Designed for demanding applications, these nuts maintain structural integrity in corrosive and high-temperature environments, making them a trusted fastening solution across petrochemical, power generation, and industrial sectors.
