INCOLOY800H/HT is an austenitic heat-resistant alloy widely used in high-temperature pressure-bearing structural parts. The high strength of 800H/HT is mainly due to the addition of carbon, aluminum, and titanium, and it is annealed at a minimum temperature of 1149℃ to achieve The grain size is ASTM5 grade or coarser.

800H can resist corrosion of many corrosive media. Its high nickel content makes it have good stress corrosion cracking resistance under water-based corrosion conditions. The high chromium content makes it have better resistance to pitting corrosion and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but its corrosion resistance in sulfuric acid and hydrochloric acid is limited. In addition to the possibility of pitting corrosion in halides, it has good corrosion resistance in oxidizing and non-oxidizing salts. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.
