When it comes to composition, the Incoloy 800/800H/800HT Bars primarily consist of nickel (30–45%), iron (32–39%), and chromium (19–23%), with small amounts of copper, carbon, and titanium thrown in. The 800H and 800HT grades have a higher carbon content and are solution-annealed to boost their high-temperature strength. These bars showcase impressive mechanical properties, with tensile strength ranging from 485–655 MPa and yield strength between 205–310 MPa. They also excel in creep, fatigue, and thermal resistance, ensuring they perform reliably under extreme temperature and pressure conditions.

Incoloy 800, 800H and 800HT bars are used in high-temperature applications where strength and oxidation resistance are crucial. They are ideal for components in petrochemical plants, power generation, and industrial heating systems. Common applications include furnace components, heat exchangers, and reactor cores. Their resistance to thermal ageing and excellent creep resistance make them suitable for severe service environments. Incoloy 800HT, with enhanced creep resistance, is specifically used in more demanding high-temperature situations.
