Incoloy 800H straight weld wires
Incoloy 800H is a nickel–iron–chromium high–temperature alloy. Its straight weld wires are designed for welding and cladding applications. They have excellent resistance to high–temperature oxidation, carburization and corrosion. The composition of Incoloy 800H straight weld wires matches the base metal. It contains 32% nickel and 21% chromium. It also has titanium and aluminum. It is suitable for both automatic and manual welding processes. These include TIG, MIG and SAW. It is often used for joining similar or dissimilar materials in high–temperature conditions.
Incoloy 800H straight weld wires are widely used in high–temperature and corrosion–resistant environments. In the energy sector, they are used for boiler piping and nuclear steam generator welding. In the petrochemical field, they are used for repairing cracking furnace tubes and resisting carburization corrosion. In the chemical industry, they are used for cladding acid–resistant containers. They are also used for welding aerospace engine parts. With excellent high–temperature strength, oxidation resistance and process adaptability, Incoloy 800H straight weld wires are ideal for extreme working conditions.
Features of Incoloy 800H straight weld wires
High–temperature stability: Incoloy 800H straight weld wires keep strength above 800°C. They have excellent anti–creep properties. They are suitable for long–term high–temperature jobs like furnace parts.
Corrosion resistance: Incoloy 800H straight weld wires resist acid media, sulfides and chloride stress corrosion. They are suitable for chemical and marine environments.
Oxidation/Carburization resistance: The chromium content forms a protective oxide layer. It prevents carbon migration at high temperatures. Incoloy 800H straight weld wires are suitable for carbon–containing equipment like cracking furnaces.
Process adaptability: Incoloy 800H straight weld wires have a wide range of wire diameters (0.8mm–3.2mm). They have high deposition efficiency. The weld seam is evenly formed. This reduces follow–up processing.
Applications of Incoloy 800H straight weld wires
Energy sector: Incoloy 800H straight weld wires are used for welding boiler pipes, heat exchangers and nuclear steam generators. They withstand high–pressure and high–temperature steam.
Petrochemical equipment: Incoloy 800H straight weld wires are used to repair cracking furnace tubes and reactor linings. They resist carburization corrosion caused by hydrocarbon cracking.
Chemical processing: Incoloy 800H straight weld wires are used for cladding container and valve sealing surfaces in sulfuric acid/nitric acid environments. They extend the life of components.
Aerospace: Incoloy 800H straight weld wires are used for welding and repairing parts in engine exhaust systems.
