L605       SPEC SHEET

Alloy L-605 (also referenced as HAYNES® 25) is the strongest of the fabricable cobalt alloys, useful for continuous service to 1800°F. Because of its long and widespread use, this alloy has been the subject of many investigations to determine its properties over a wide range of conditions, thus making it an unusually well characterized material. When exposed for prolonged periods at intermediate temperatures, alloy L-605 exhibits a loss of room temperature ductility in much the same fashion as other superalloys, such as alloy X or alloy 625.
