Hastelloy C-4 / UNS N06455 for Hot Mineral Acids, Chlorine-Containing Medium, High Temp Metal

HASTELLOY C-4 alloy is a nickel-chromium-molybdenum alloy with outstanding
high-temperature stability as evidenced by high ductility and corrosion resistance even after aging in the 1200 to 1900 °F (649 to 1038°C) range. This alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition. C-4 alloy also has excellent resistance to stress-corrosion cracking and to oxidizing atmospheres up to 1900°F (1038°C).

HASTELLOY C-4 alloy has exceptional resistance to wide variety of chemical process environments. These include hot contaminated mineral acids, solvents, chlorine and chlorine contaminated media (organic and inorganic), dry chlorine, formic and acetic acids, acetic anhydride, and seawater and brine solutions.
