K213

K213 is an iron-based precipitation hardening equiaxed grain casting superalloy, which is mainly formed by adding aluminum and titanium‘ γ’ Precipitation strengthening phase, adding a certain amount of chromium and tungsten for solid solution strengthening, and adding an appropriate amount of boron to strengthen the grain boundary.
