The Incoloy 800/800H/800HT alloys are primarily made up of nickel (30–45%), iron (32–39%), and chromium (19–23%), with a few minor additions of copper, carbon, and titanium. The 800H and 800HT grades stand out with their higher carbon content and are solution-annealed to enhance their high-temperature strength. These alloys are known for their impressive mechanical properties, featuring tensile strength between 485–655 MPa and yield strength from 205–310 MPa. They excel in resisting oxidation, carburization, and stress corrosion cracking, while also offering remarkable creep and fatigue resistance, ensuring they perform reliably even under extreme temperatures and pressures.
