ASTM B515 Incoloy 800H Chemical Resistant Seamless Pipe

01.

ASTM B515 Incoloy 800H is a nickel-iron-chromium seamless tubing known for its excellent resistance to high-temperature oxidation and corrosion in aggressive chemical environments. It offers high strength at elevated temperatures, good weldability, and low-temperature toughness. Compared to the base alloy, 800H has a higher carbon content, resulting in increased high-temperature strength, making it suitable for demanding applications such as chemical processing, power generation, and oil and gas.

About Gnee Steel

Gnee Steel specializes in the production of various nickel-based alloys. Gnee Steel's product packaging includes steel strapping: Pipes with an outer diameter of 3 inches or less are typically strapped together with polypropylene film to prevent rust during sea transportation, and then secured with steel strapping. Wooden boxes/crates: Pipes are typically packaged in wooden boxes or crates to protect them during transportation, especially those that are longer or have larger diameters. Seaworthy export packaging: Suppliers typically use standard seaworthy export packaging methods, which may include a variety of materials and techniques to protect the pipes during transportation. Tarpaulin packaging: This prevents rain, seawater, and other external factors from penetrating the export wooden crates during transportation. Gnee Steel specializes in the production and sale of alloy materials. Gnee Steel's products are widely used in aerospace, chemical, power, automotive, and nuclear energy industries, and we can provide customized alloy material solutions based on customer needs.
