Characteristics of Incoloy 800 Tube

Incoloy 800 tube is a nickel-iron-chromium alloy with excellent oxidation, sulfidation and carburization resistance. It has high strength and good corrosion resistance in high and low-temperature environments. The alloy can also be used in harsh applications such as acidic chloride and alkaline salt solutions, making it the perfect choice for heat exchangers, condensers, evaporators, combustion chambers, thimbles, etc. Its advantages include great hot workability when annealed; superior stress rupture properties; excellent creep-rupture strength; capability of achieving temperatures up to 1260°C (2300°F); no embrittlement after welding or thermal shock; outstanding formability at room temperature & very good weldability.

Applications of Incoloy 800 Tube

Incoloy 800 Tube is a nickel-iron-chromium alloy with excellent high-temperature corrosion resistance. It has excellent thermal stability and retains strength even after long exposure to elevated temperatures. Its primary applications include heat exchangers, condensers, storage tanks, and piping systems in oil refineries, nuclear power plants, chemical processing plants, industrial furnaces and more. Its superior creep and stress rupture properties make it an ideal choice for high-temperature components operating under pressure, such as valves or structural components. It is also often selected due to its excellent resistance to sulfur compounds at high temperatures, making it an essential material for pipeline networks transporting acidic liquids or gases. Furthermore, the continuous use at 1200°F (649°C) provides a major advantage over austenitic steels when utilized in welded structures with similar grain size control requirements.
