Varun Sheets and Plates is a reliable manufacturer and supplier of Incoloy 800 / 800H / 800HT Coil and Slitting Coil, proudly based in Dubai, UAE. We specialize in high-performance nickel-iron-chromium alloy coils that are engineered for outstanding strength, thermal stability, and impressive resistance to oxidation and carburization, even in high-temperature settings. These coils find their way into various applications, including heat treating equipment, petrochemical processing, power generation, and furnace components. Adhering to ASTM B409 standards, our Incoloy 800 series coils come in a range of tempers, thicknesses, and widths, along with precision slitting services tailored to meet the specific needs of customers both in the UAE and around the globe.
Typically, Incoloy 800 / 800H / 800HT Coils are made up of 30–35% nickel, 19–23% chromium, and small amounts of aluminum and titanium. The 800H and 800HT versions are designed to offer improved creep and rupture strength thanks to their carefully controlled carbon and aluminum/titanium content. These alloys excel in resisting oxidation, carburization, and stress corrosion cracking, boasting tensile strength between 450 to 650 MPa and reliable performance at temperatures reaching up to 1100°C (2012°F).
