Stacking fault energy and stacking fault nucleation energy are defined in terms of the physical nature of stacking faults and stacking fault energy and the measuring basis for stacking fault energy. Large quantities of experimental results are processed with the aid of a computer and an expression for calculating stacking fault energy has been obtained as γ300SF (mJ m-2) = γ0SF + 1.59Ni - 1.34Mn + 0.06Mn2 - 1.75Cr + 0.01Cr2 + 15.21Mo - 5.59Si -60.69(C + 1.2N)1/2 + 26.27(C + 1.2N)(Cr + Mn + Mo)1/2 + 0.61[Ni·(Cr + Mn)]1/2.
