For Severely Sulfidizing and Other Aggressive Environments
HAYNES® 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 at corrosion attack by low melting point compounds such as those formed by phosphorus, vanadium, and other impurities. HR-160 alloy utilizes high chromium and silicon contents to form a protective oxide scale which renders the alloy resistance to various forms of high-temperature corrosion.
Alloy Description
HAYNES® HR-160® alloy is a Ni-Co-Cr-Si alloy with a stable austenitic structure. The alloy is readily fabricated, and may be welded by gas-tungsten-arc (TIG) or gas-metal-arc (MIG) techniques. 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. HAYNES® HR-160® alloy is available as plate, sheet, strip, billet, bar, wire, pipe, and tubing.
