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).HR-160® alloy is furnished in the solution-annealed condition, unless otherwise specified.

ASME Vessel Code
HR-160® is covered in ASME Section VIII Division 1 for construction up to 1500°F (815°C). Code Case 2385 covers HR-160® for construction up to 1800°F (982°C). The thickness of the plate at welded joints is limited to 0.50 inches.
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.
