| Abstract Scope |
HAYNES 233 alloy was developed to fill a need in the marketplace for a readily fabricable superalloy with both excellent oxidation resistance and high creep strength at temperatures up to 2100°F (1149°C). While there are a number of fabricable alloys with high creep strength at these temperatures (230® alloy, 617 alloy, etc.), they generally rely on chromia-formation to provide oxidation resistance. Conversely, existing fabricable alloys (such as 214® alloy) which have sufficient Al to produce a protective alumina scale generally suffer from poor creep strength at temperatures above the gamma-prime solvus. The new 233 alloy combines both properties while still having the capability to be welded, hot worked, cold worked, etc. The development of 233 alloy will be presented along with some details of the alloy research which led to its invention. |
