Inconel 800, 800H & 800HT Plates Manufacturer, Supplier & Exporter
Inconel 800, 800H, and 800HT plates are nickel-iron-chromium alloy plates designed for high-temperature oxidation resistance, carburization resistance, and excellent mechanical strength. While all three grades belong to the same alloy family, Inconel 800 (UNS N08800) offers excellent corrosion resistance, Incoloy 800H Plate (UNS N08810) provides higher creep and rupture strength due to controlled carbon content, and Inconel 800HT Sheet (UNS N08811) delivers enhanced elevated-temperature performance through optimized titanium and aluminum levels. These alloys are widely used in heat exchangers, petrochemical plants, power generation, pressure vessels, and furnace components.
