Description
Alloy 800/H/HT(Incoloy® 800/800H/800HT, UNS N08800/N08810/N08811, W. Nr. 1.4876, 1.4958, 1.4959) is an iron-nickel-chromium alloy with moderate strength and good resistance to oxidation and carburization at elevated temperatures. It is particularly useful for high-temperature equipment in the petrochemical industry because the alloy doesn't form the embrittling sigma phase after long time exposure at 1200°F (649°C). Excellent resistance to chloride stress-corrosion cracking is another important feature of alloy 800. Alloy 800H is a solution heat treated (2100°F/1150°C), controlled-carbon version of alloy 800 with improved elevated temperature properties. It has improved creep and stress-rupture characteristics in the 1100°F (593°C) to 1800°F (982°C) temperature range.
Applications
heat exchangers and process piping,
furnace components,
ammonia effluent coolers,
carburizing fixtures and retorts
