Incoloy 800, 800H, and 800HT Forged Fittings contain nickel, iron, and chromium with different carbon contents and heat treatment for diverse high-temperature purposes. Incoloy 800 provides good strength and oxidation resistance to around 1100°C, whereas the 800H and 800HT grades possess more carbon and are solution annealed for offering better creep and tensile strength at elevated temperatures. The fittings usually offer tensile strengths between 485 MPa and 620 MPa and possess outstanding resistance to thermal fatigue, stress corrosion cracking, and carburization. Their high ductility and resistance to impact guarantee long-term stability under heat stress.
