Resistance to High-Temperature Corrosion
HAYNES® HR-160® 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 lowgrade fuels or processing of chemical feedstocks 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).
Ease of Fabrication
HAYNES HR-160 alloy has excellent forming and welding characteristics. It may be forged or otherwise hot-worked, providing it is held at 2050°F (1121°C) for time sufficient to bring the entire piece to temperature. As a consequence of its good ductility, HR-160 alloy is also readily formed by cold working. Cold- or hot-worked parts should be annealed and rapidly cooled in order to restore the best balance of properties.
HR-160 alloy can be welded by a variety of techniques, including gas tungsten arc (TIG), gas metal arc (MIG), and resistance welding.
Heat-Treatment
HR-160 alloy is furnished in the solution annealed condition, unless otherwise specified. The alloy is solution annealed at 2050°F (1121°C) and rapidly cooled for optimum properties. Intermediate annealing, if required during fabrication and forming operations, can be performed at temperatures as low as 1950°F (1066°C).
Available in Practical Product Forms
HAYNES HR-160 alloy is available in the form of plate, sheet, strip, billet, bar, wire, pipe, and tubing.
Applications
HAYNES HR-160 alloy combines properties which make it highly useful for service in severe high-temperature corrosive environments. Applications include a variety of fabricated components in municipal, industrial, hazardous, and nuclear waste incinerators. It is widely used in recuperators, heat exchangers and waste heat recovery systems. HR-160 alloy is also suitable for utility boilers, sulfur plants, high-temperature furnaces, kilns, calciners, resource recovery units, cement kilns, pulp and paper recovery boilers, coal gasification systems, and fluidized-bed combustion systems.
Applicable Specifications
The UNS number for HAYNES HR-160 alloy is N12160.
ASME Vessel Code
HAYNES HR-160 alloy is covered by ASME Vessel Code case No. 2162 for Section VIII Division 1 construction to 1500°F (816°C).
