Nickel-based GH3030 high-temperature alloy tube description

GNEE Nickel-based GH3030 high-temperature alloy tube
Nickel-based superalloy GH3030 (also known as UNs GH30, XH78Tor Inconel 3030) is a solid solution strengthened superalloy, mainly used in applications where temperatures reach up to 800℃ and high thermal strength and oxidation resistance are required.
GH3030 is a high-temperature alloy, also known as Inconel 713C. It is a nickel-based superalloy with excellent high-temperature strength, oxidation resistance, and creep resistance. This alloy contains significant amounts of nickel, chromium, and aluminum, as well as trace amounts of other elements such as iron, cobalt, and titanium.
GH3030 tubing is commonly used in applications requiring high-temperature resistance, such as gas turbines, aerospace components, and industrial furnaces. These tubings can withstand temperatures up to approximately 1100°C (2012°F) while maintaining their mechanical properties.
