The **Incoloy 800/800H/800HT Bars** are primarily made up of nickel (30–35%), iron (at least 39.5%), and chromium (19–23%), with carefully controlled levels of carbon, titanium, and aluminum to boost high-temperature strength and creep resistance. The 800H variant is designed for enhanced strength at elevated temperatures, while the 800HT version excels in creep and oxidation resistance under extreme heat. These bars demonstrate tensile strengths between 500–700 MPa, along with excellent ductility and outstanding resistance to scaling, oxidation, and corrosion, making them ideal for long-term use in harsh industrial and high-temperature settings.
