Description
Haynes HR-160
HAYNES® HR-160® (UNS N12160) alloy is a solid-solution-strengthened nickel-cobalt chromium-silicon alloy with outstanding resistance to various forms of high temperature corrosion attack. HR-160® alloy has excellent resistance to sulfidation and chloride attack in both reducing and oxidizing atmospheres. The alloy also has exceptionally good resistance to oxidation, hot corrosion, carburization, metal dusting, nitridation, and corrosion attack by low melting point compounds such as those formed by phosphorus, vanadium, and other impurities. The alloy is especially suited for applications in high temperature corrosive environments generated by combustion of low grade fuels or processing of chemical feed stocks with corrosive contaminants such as sulfur, chlorine, fluorine, vanadium, phosphorus, and others. The alloy is capable of withstanding temperatures up to 2200°F (1204°C).
