Audited Supplier K213 is an iron-based precipitation hardening equiaxed crystal casting superalloy. It is mainly formed by adding aluminum and iron elements to form a Y precipitation strengthening phase, adding a certain amount of chromium and tungsten elements for solid solution strengthening, and adding an appropriate amount of boron element to strengthen the grain boundary. The alloy has good casting properties, and has good comprehensive properties and microstructure stability below 750 °C. It is mainly used to make mobile and stationary blades of supercharger turbines, gas turbines and flue gas turbines working below 750°C.
The casting properties and microstructure stability of the alloy are good. After long-term aging at 700ºC for 2000h, only a small amount of Laves phase precipitates.
