Haynes International, Inc. is pleased to announce the development of HAYNES® HR-224® alloy, a new alloy with excellent oxidation resistance and improved fabricability and weldability compared to HAYNES® 214® alloy. This Ni–27.5Fe–20Cr–3.8Al alloy achieves superior oxidation resistance through the formation of a tightly adherent alumina protective scale. It exhibits excellent ductility and formability characteristics, with weldability on par with nickel-iron-chromium alloys of substantially lower aluminum contents. Potential uses include applications in heat recuperators, automotive catalytic converters and heat shields, strand annealing furnace tubulars, and other severely oxidizing environments.
*Average Metal Affected = Metal Loss + Average Penetration; Maximum Metal Affected = Metal Loss + Maximum Internal Penetration
HAYNES® HR-224® alloy will become available for commercial sale upon completion of key process developments. It is being manufactured in a variety of forms, including sheet, plate, bar, structural and weld wire, and welded tubular products. Material for trial evaluations and fabrications is available.
