Detailed explanation of Incoloy 800/800H/800HT heat exchanger/condenser tubes
Incoloy 800, 800H, and 800HT tubes are nickel-iron-chromium alloys widely used in the manufacture of heat exchanger tubes due to their excellent strength and resistance to high-temperature corrosion, oxidation, and carburization. The main differences between them lie in the content of carbon, aluminum, and titanium, which are optimized to suit different temperature ranges and mechanical property requirements.
What is 800H?
800H/800HT alloys are high-strength, high-temperature alloys used as alternatives to the commonly used 600 series alloys. They have widespread applications in numerous industries, including aerospace, petrochemicals, and chemical processing. Due to their high strength characteristics, they can be used in demanding environments where other alloys would fail.
Incoloy is a high-nickel superalloy with excellent corrosion resistance and high-temperature strength. It is the ideal material for manufacturing high-quality heat exchangers. Gnee Steel is a leading exporter, manufacturer, and supplier of Incoloy 800/800H/800HT heat exchanger/condenser tubes, providing high-quality products to domestic and international customers. Gnee Steel sources its raw materials from reputable suppliers who provide quality assurance and other services. Due to its superior service, Gnee Steel has become the preferred choice for customers purchasing heat exchangers.
