Content

Incoloy 800H/HT alloy is used for high temperature structural applications. The nickel content makes the alloy highly resistant to chloride stress corrosion cracking and embrittlement from sigma-phase precipitation. Overall corrosion resistance is excellent. Alloys 800H and 800HT have excellent creep and stress rupture properties under solution annealed conditions. Meanwhile, Incoloy 800HT Perforated Coils have a restricted chemical composition, within the limits of Incoloy 800H Perforated Coils, and require a heat treatment of at least 2100 degrees Fahrenheit (1149 degrees Celsius). Alloy 800HT coils are also used in valves, fittings and other components that are subject to corrosion from 1100¡ãF to 1800¡ãF.
