Incoloy 800H Nickel Based tube
Incoloy 800H Nickel Based tube is a high-performance nickel-iron-chromium based alloy tube. It is reinforced by adding elements such as aluminum and titanium to enhance its oxidation resistance and creep resistance. Incoloy 800H Nickel Based tube meets standards like ASTM B407 and ASTM B163. It is designed for extreme high-temperature and corrosive environments. The alloy contains about 30-35% nickel and 19-23% chromium. It also has a small amount of carbon (0.05-0.10%) to improve high-temperature strength.
Incoloy 800H Nickel Based tube is widely used in petrochemical cracking furnaces, heat exchangers, and nuclear power steam pipes. It can withstand sulfidation and carburization corrosion. It performs well in power boilers, industrial heating furnaces, and waste heat recovery systems. It is suitable for the fields of metallurgy, glass manufacturing, and environmental incineration. It combines durability and cost-effectiveness.
Features of Incoloy 800H Nickel Based tube
Excellent high-temperature performance: Incoloy 800H Nickel Based tube can work for a long time above 700°C. It has excellent creep and tensile strength. It is suitable for thermal cycling conditions.
Corrosion resistance: The high chromium content of Incoloy 800H Nickel Based tube gives it the ability to resist oxidation, sulfidation, and carburization. It is suitable for acidic, alkaline, and sulfur-containing environments.
Workability and weldability: Incoloy 800H Nickel Based tube can be processed by hot and cold forming. It supports conventional welding methods such as TIG and MIG. But heat input needs to be controlled to avoid intergranular corrosion.
Stability: Incoloy 800H Nickel Based tube gets a uniform austenitic structure through solution annealing. This ensures its structural stability and long service life.
Applications of Incoloy 800H Nickel Based tube
Petrochemical: Incoloy 800H Nickel Based tube is used in cracking furnace tubes, heat exchangers, and catalytic reforming units. It can withstand high temperature, high pressure, and corrosive media.
Energy and power: Incoloy 800H Nickel Based tube is used in key parts such as boiler superheaters and nuclear power steam generator pipes.
Industrial heating: Incoloy 800H Nickel Based tube is used as radiant tubes and muffle furnace linings. It plays an important role in the metallurgy and glass manufacturing industries.
Environmental protection: Incoloy 800H Nickel Based tube is used in waste heat recovery systems and incinerator pipes. It can resist the corrosion of acidic exhaust gases.
