Unlike CF8M and CF3M of ASTM A351, CF8C grade has option for stabilization treatment due to Nb present which forms carbides, between 870 and 900 °C after solution annealing in austenite matrix. This prevents depletion of chromium around grain boundary and prevents sensitization of steel. However, this stabilization treatment …
