Tanvir Nickel Alloys, located in Cairo, Egypt, is a reputable manufacturer and supplier of Incoloy 800, 800H, and 800HT tubing, specifically crafted to handle the tough demands of high-temperature and corrosive industrial settings. With a wealth of experience in nickel-iron-chromium alloys, Tanvir delivers precision-engineered tubing that meets international quality standards for dimensional accuracy, surface finish, and mechanical properties. These tubes find extensive use in industries such as petrochemical, power generation, heat treatment, and chemical processing, providing dependable performance and durability even in extreme conditions, both locally and internationally.
The Incoloy 800 series tubing primarily consists of nickel (30–35%), chromium (19–23%), and iron, along with carefully controlled amounts of carbon, aluminum, and titanium. Incoloy 800 is known for its excellent resistance to oxidation and carburization at high temperatures, while 800H has a higher carbon content that boosts its creep and rupture strength. Incoloy 800HT stands out with its enhanced high-temperature stability and strength, thanks to optimized levels of carbon, aluminum, and titanium. These tubes typically exhibit tensile strengths ranging from 500 to 650 MPa and can reliably operate at temperatures up to 1100°C (2010°F), making them perfect for high-stress, high-temperature applications.
