L605 Alloy for Sheet, Plate, & Bar
(AMS 5537, AMS 5759, UNS R30605)
Alloy L605, also called HAYNES® 25 and Cobalt L-605, is a solid solution, cobalt-nickel-chromium-tungsten alloy that is useful for continuous service to 1800°F (980°C). The L605 alloy is the strongest of the fabricable cobalt alloys and has been the subject of many investigations to determine its properties over a wide of conditions because of its long and widespread use. L605 alloy exhibits a loss of room temperature ductility in much the same way as other superalloys, such as alloy X or alloy 625, when exposed for prolonged temperatures at intermediate temperatures. L605 alloy from Altemp is specified to AMS 5537 & 5759.
