Incoloy 800H polished bar
Incoloy 800H polished bar is a nickel–iron–chromium-based superalloy. It has been specially annealed and polished. This forms a bar with a smooth surface and precise dimensions. The core components of Incoloy 800H polished bar are nickel (30–35%), chromium (19–23%), and iron (≥39.5%). It also contains titanium (0.15–0.6%) and aluminum (0.15–0.6%). These additions improve stability. The polishing process reduces surface roughness. It makes the bar both good-looking and functional. It is suitable for high-standard industrial settings.
Incoloy 800H polished bar is widely used in high-temperature and corrosion-resistant environments. These include chemical reactors, nuclear power heat exchangers, gas turbine parts, and industrial furnace components. The bar has excellent high-temperature strength and oxidation resistance. Its polished surface also has special properties. This makes it suitable for precision instruments, aerospace fasteners, and acid treatment equipment. It meets the reliability and durability needs in tough working conditions.
Features of Incoloy 800H polished bar
Excellent high temperature performance: Incoloy 800H polished bar still has excellent oxidation and creep resistance at up to 815°C. This is due to its high chromium content and stable austenitic structure.
Corrosion resistance: Incoloy 800H polished bar has significant resistance to carburization, nitriding and sulfuric/nitric acid environments. It is suitable for chemical and energy fields.
Machining optimization: The polished surface of Incoloy 800H polished bar reduces surface defects and increases fatigue life. It also lowers the coefficient of friction. This makes it easier for follow-up precision machining.
Good weldability: Incoloy 800H polished bar supports common welding processes such as TIG and MIG. Heat treatment is needed after welding to restore properties.
Applications of Incoloy 800H polished bar
Energy industry: Incoloy 800H polished bar is used in gas turbine combustion chamber components and nuclear power heat exchanger pipes. It can endure high temperature, high pressure and corrosion.
Chemical equipment: Incoloy 800H polished bar is used to make acid treatment equipment and reactor bolts. It can deal with highly corrosive media.
Industrial furnace components: Incoloy 800H polished bar is used to make components such as radiant tubes and muffle cans. It can work stably in extreme thermal cycling environments for a long time.
Aerospace: Incoloy 800H polished bar is used in rocket engine nozzle support components. It meets the needs for both light weight and heat resistance.
