Haynes 233 Alloy Sheet
Haynes 233 alloy plate is a new nickel-cobalt-chromium-molybdenum-aluminum alloy that achieves excellent oxidation resistance through the formation of a protective alumina layer. At the same time, its high creep strength comes from solid solution strengthening and carbide strengthening.
Additionally, for use at low to intermediate temperature applications (below the gamma-prime solvus of 1767°F (964°C)), the Haynes 233 alloy sheet 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 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.

Heat Treatment Sheet
Haynes 233 alloy sheet is supplied in the mill (solution) annealed condition and may be used in either the solution annealed or age-hardened condition, depending on application. Solution annealing is typically performed by heating to a temperature in the range of 2100 to 2150°F (1149 to 1177°C) for a time commensurate with thickness, followed by a water quench. The solution annealed condition is most appropriate for applications above 1767°F (964°C). Alloy 233 can be age-hardened to significantly increase strength at low to intermediate temperatures (below the gamma-prime solvus of 1767°F (964°C)). A typical age-hardening heat treatment for this alloy is 1650°F/4h/AC + 1450°F/8h/AC (899°C/4h/AC + 788°C/8h/AC).
Application
- Hot gas components in aerospace and industrial gas turbines
- Industrial heating fixtures and sensors
- Various structural components in the emerging technology market
