L605 Alloy Powder Description
L605 Alloy (UNS R30605) Powder is a non-magnetic, cobalt-based alloy. The alloy L605 retains its strength up to 2 150°F. L605 requires a minimum yield strength of 45 000 psi at ambient temperature. It exhibits oxidation resistance up to 1 900°F. It is capable of resisting corrosion in extremely challenging environments. The alloy shows high resistance to hydrochloric acid, nitric acid and wet chlorine, and it also exhibits resistance to sulfidation as well as wear and abrasion.

L605 Alloy Powder Applications
L605 Alloy Powder is employed in the hot sections of aircraft and land turbine combustion chambers. It is also used in other applications that require moderate strength and oxidation resistance at elevated temperatures. L605 Alloy is the formable cobalt alloy with the highest strength and is suitable for continuous operation at temperatures up to 1 800°F. The alloy has been the subject of multiple studies across various conditions, resulting in a detailed quantification of its properties. It may also be used in industrial ovens, for example in muffle furnaces and high-temperature oven linings.
