Tanvir Nickel Alloys, located in Cairo, Egypt, is a reputable manufacturer and supplier of Incoloy 800, 800H, and 800HT bars, celebrated for their outstanding performance in high-temperature and corrosive settings. With years of experience in nickel-iron-chromium alloys, the company provides precision-machined bar stock that adheres to international standards for strength, heat resistance, and metallurgical stability. These bars find extensive applications in thermal processing, petrochemical systems, and power generation equipment, where reliable performance under prolonged heat exposure is essential. Tanvir Nickel Alloys guarantees that each bar is crafted with tight tolerances and a superior surface finish, making them ready for demanding applications both locally and internationally.
The Incoloy 800 series bars primarily consist of nickel (30–35%), chromium (19–23%), and iron, along with small amounts of carbon, aluminum, and titanium. Incoloy 800 is known for its excellent resistance to oxidation and carburization at high temperatures, while 800H, which has a higher carbon content, offers enhanced creep and rupture strength. Incoloy 800HT takes high-temperature performance a step further with carefully controlled levels of carbon, aluminum, and titanium. These bars demonstrate tensile strengths ranging from 500 to 650 MPa and maintain remarkable mechanical stability at temperatures up to 1100°C (2010°F), making them ideal for structural and pressure-bearing applications.
