Incoloy 800, 800H, and 800HT forged fittings are well recognized for their superior chemical, mechanical, and physical properties to be highly appropriate for corrosive and high-temperature environments. Chemically, the alloys are mostly composed of nickel, iron, and chromium, whereas Incoloy 800H and 800HT have slightly more carbon content along with enhanced creep strength. Mechanically, they provide superior tensile strength, excellent weldability, and thermal fatigue and oxidation resistance. The alloys can resist very high temperatures up to 1100°F (593°C) and have good resistance to stress-corrosion cracking, guaranteeing strength under high-pressure as well as high-temperature conditions. Physically, Incoloy 800, 800H, and 800HT have good thermal conductivity and low expansion, along with improved strength retention at high temperatures, and are therefore best suited for applications in heat exchangers, boilers, and other high-stress industrial processes.
