Haynes International announce development of HAYNES 233 alloy
Haynes International is pleased to announce the development of HAYNES(R) 233(TM) alloy. This alloy is expected to have excellent oxidation resistance coupled with superior creep strength at temperatures up to 2100 degrees F (or higher) - a combination of properties never before achieved in a readily fabricated alloy. The alloy achieves 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 exhibiting very good hot workability, cold formability and weldability. Potential uses include applications in the aerospace and industrial gas turbine, industrial heating, and emerging technology markets. Material is expected to be available for trial evaluation as manufacturing progresses. Planned product forms include sheet, plate, billet, bar, wire, pipe, and tube.
