Lork Group high-quality Haynes 233 is a new Ni-Co-Cr-Mo-Al alloy that offers excellent oxidation resistance at temperatures to 2100°F (1149°C) or higher, depending on application, coupled with superior creep strength – a combination of properties never before achieved in a readily fabricable alloy.

Haynes 233 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 at low to intermediate temperature applications (below the gamma-prime solvus of 1767°F (964°C)), the alloy can be age-hardened by heat treatment to produce even greater strength.

Finally, Haynes 233 can be readily fabricated using conventional methods since it exhibits good hot workability, cold formability, and weldability. Potential applications include hot gas path components in aerospace and industrial gas turbines, industrial heating fixtures and sensors, and various structural components in the emerging energy and chemical process markets.
