About Incoloy 800 / 800H / 800HT
Inconel 800, 800H and 800HT (UNS N08800/N08810/N08811) for high-temperature petrochemical and power-generation service.
Incoloy 800 (UNS N08800) is an iron-nickel-chromium alloy with 30–35% nickel and 19–23% chromium for carburisation and oxidation resistance to about 815 °C. The 800H (N08810) and 800HT (N08811) variants use controlled carbon and a coarse grain size to deliver far higher creep and stress-rupture strength for service between 600 °C and 1100 °C.
Steelco Metal & Alloys stocks Incoloy 800 / 800H / 800HT (UNS N08800 / N08810 / N08811) in Mumbai, India as a stockist, importer and exporter, and ships to 40+ countries. Every dispatch carries EN 10204 3.1 (3.2 on request) mill test certificates, PMI verification and is open to third-party inspection.
