Incoloy 800/800H/800HT Pipe Fittings Supplier, Exporter & Manufacturer in Mumbai, India

Incoloy 800, 800H & 800HT Pipe Fittings are manufactured from nickel-iron-chromium alloys developed to deliver dependable performance in high-temperature industrial environments where heat resistance, oxidation protection, and structural stability are essential. These alloys are valued for their ability to retain useful mechanical properties at elevated temperatures and resist oxidation and carburization under suitable operating conditions. Nickel provides the foundation for corrosion and heat resistance, chromium supports oxidation protection, and iron contributes to the alloy’s overall composition. Incoloy 800H and 800HT are specifically designed for improved high-temperature strength and creep resistance compared with standard Incoloy 800, making the appropriate grade selection important for each application. These pipe fittings are suitable for petrochemical processing plants, thermal processing systems, industrial furnaces, heat exchangers, power generation facilities, and high-temperature piping networks, where reliable connections, dimensional integrity, and long-term service performance are important.
