Incoloy 800/800H/800HT Tubing is made up of nickel (30–35%), chromium (19–23%), and iron as the primary components, with added aluminum and titanium to boost stability. The 800H grade has a controlled higher carbon content for enhanced creep strength, while the 800HT grade is optimized with aluminum and titanium for exceptional high-temperature performance. These grades offer remarkable mechanical strength, oxidation resistance, and stability at elevated temperatures. They maintain good tensile strength, stress-rupture properties, and resistance to carburization, scaling, and chloride-induced corrosion, making them perfect for challenging heat-intensive operating conditions.
