Incoloy 330 square plate
Incoloy 330 square plate is a high nickel-chromium austenitic heat-resistant alloy. It is known for its excellent resistance to high-temperature oxidation and carburization. The plate is made by hot or cold rolling. It has standard sizes like 1m×1m or 2m×2m and customized thicknesses from 3mm to 50mm. The surface can be polished, pickled or sandblasted to meet different industrial needs.
Incoloy 330 square plate is widely used in high-temperature corrosive environments. It is used for radiant tubes and annealing trays in heat treatment furnaces. It is also used for parts in chemical cracking furnaces and linings in waste incinerators. Its excellent resistance to carburization and oxidation makes it suitable for nuclear power heat exchangers and aerospace heat-resistant components. It is a reliable choice for high-temperature industrial equipment.
Features of Incoloy 330 square plate
High-temperature resistance: Incoloy 330 square plate stays stable in continuous high-temperature environments up to 1150℃ and can withstand 1200℃ for short periods.
Corrosion resistance: The high nickel (34-37%) and chromium (17-20%) content of Incoloy 330 square plate effectively resist oxidation, carburization, and sulfidation corrosion.
Mechanical strength: Incoloy 330 square plate has good high-temperature creep rupture strength and is suitable for withstanding thermal cycling stresses.
Processability: It can be welded, cut, and formed, but the risk of cracking due to cold working hardening should be avoided.
Applications of Incoloy 330 square plate
Heat treatment industry: Incoloy 330 square plate is used to make furnace chamber components, radiant tubes, and annealing furnace guides for core parts of high-temperature equipment.
Chemical industry: Incoloy 330 square plate is used in ethylene cracking furnaces and ammonia synthesis units to resist carburization and acidic atmosphere corrosion.
Energy and environmental protection: Incoloy 330 square plate is used for waste incinerator linings and nuclear power heat exchanger plates to cope with harsh thermal environments.
Aerospace: Incoloy 330 square plate is used for engine nozzle heat shield supports to reduce weight and improve durability.
