Elgiloy Specialty Metals is excited to announce the expansion of our extensive list of mission-critical, high-performance alloys with the addition of two new alloys:

About HAYNES® 233™ alloy

HAYNES® 233™ alloy is a new Ni-Co-Cr-Mo-Al alloy that offers excellent oxidation resistance at temperatures up to 2100°F (1149°C) or higher coupled with superior creep strength – a combination of properties never before achieved in a readily fabricable alloy. The alloy obtains its exceptional oxidation resistance through the formation of a protective alumina layer, while the high creep strength is a result of solid-solution and carbide strengthening. Additionally, for use in intermediate temperature applications the alloy can be age-hardened by heat treatment to produce even greater strength.

Finally, the alloy can be readily fabricated using conventional methods since it exhibits good hot workability, cold formability, and weldability.

Potential applications include:

• hot gas components in aerospace and industrial gas turbines
• industrial heating fixtures and sensors
• various structural components in the emerging technology market

Industries supplied:

• Aerospace
• Industrial Heat Treating
• Power Generation

This is the first time this alloy has been produced in light gauge strip product. We expect demand for this alloy to increase and anticipate growth for this alloy as feedstock becomes more available and new applications emerge.

About HAYNES® HR-224® alloy

HAYNES® HR-224® alloy is a wrought Ni–27.5Fe–20Cr–3.8Al alloy with excellent oxidation resistance and improved fabricability and weldability compared to HAYNES® 214® alloy. This 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 applications include:

• heat recuperators
• automotive catalytic converters
• heat shields
• strand annealing furnace tubulars
• fuel cells
• gas separation units
• applications requiring minimal chromia vaporization & other severely oxidizing environments

Industries supplied:

• Automotive
• Industrial Heat Treating
• Chemical Processing
