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, and various structural components in the emerging technology market. Preliminary results from mill products are provided below.
This product will be available in various forms including sheet, plate, billet, bar, wire, etc. Sample material is available upon request. For more information on 233™ alloy, please contact Vinay Deodeshmukh at (765) 456-6212 or VDeodeshmukh@haynesintl.com.
