HAYNES® HR-160® alloy provides the best combination of resistance to harsh, high-temperature environments and life cycle cost effectiveness of any commercially available alloy. Components produced from HR-160 alloy have exhibited outstanding performance in waste incineration applications. Field trials have demonstrated that component life extensions greater than 10X are possible with direct material substitution. HR-160 alloy utilizes high chromium and silicon contents to promote the formation of a protective oxide scale which resists attack from sulfur, vanadium, chlorides, and other salt deposits. This makes the alloy ideally suited for waste incinerator components operating up to 2200°F (1204°C), such as T/C protection tubes, dampers, tube shields, tube supports, thermos wells, combustion chambers, ducts, heat exchangers, and vortex finders.
HAYNES HR-160 alloy is a Ni-Co-Cr-Si alloy with a stable austenitic structure. The alloy is easily fabricated using methods such as gas-tungsten-arc welding (TIG) process or gas-metal-arc welding (MIG) process. HR-160 filler metal is recommended for joining HR-160 alloy; when HR-160 alloy is welded to other alloys, such as stainless steels, 556® filler metal should be used.
