ASTM B366 N08810 N08820 Equal Tee Incoloy 800H/800HT Tee, High Temp Corrosion Resistant For Piping System

ASTM B366 N08810 & N08820 equal diameter tees are special alloy pipe fittings designed to withstand extremely harsh high-temperature, high-pressure, and corrosive conditions, fundamentally solving the connection problems of core piping systems in the petrochemical, energy, and high-end manufacturing industries.

800H (N08810) - High-Temperature Reinforced Version: By specially increasing the carbon content (0.05%-0.10%) and combining it with high-temperature solution treatment, coarse austenitic grains are obtained, resulting in excellent creep resistance and end-of-life fracture strength at high temperatures. Due to its high chromium and high nickel content, it exhibits excellent resistance to stress corrosion cracking in corrosive media such as chlorides and high-temperature, high-pressure water.

800HT (N08820) - Enhanced High-Temperature Performance: Based on 800H, by more strictly controlling the content of carbon, aluminum, and titanium, its creep rupture strength at high temperatures is higher than that of 800H, while maintaining good strength and excellent resistance to oxidation and carburization.
