What is Hardness of Superalloys – Inconel - Material Properties
WebJan 1, 2015 · The heat treatment applied to Inconel 718, precipitation hardening, has two steps: solid solution and aging treatment. In first step the secondary (hardening) phases are dissolved along the matrix, as well as carbides. It is important to note that after 650 °C (Durand-Charre in The microstructure of superalloys. WebThe heat treatment for Inconel 718, like Inconel 725, is age hardening, and this material can be used as an option for valve stems. If the mechanical strength of 25Cr super duplex for the stem is not high enough, the stem material can be upgraded to an alloy with higher mechanical strength, such as Inconel 718 or 725.
