Description	Within the optimization of material processing technology for heavy forgings made from the steel SA 508 for power industry (especially shafts), kinetics of grain growth, recrystallization and precipitation processes in order to prevent the occurrence of coarse-grained structures were evaluated. In the typical range of forging temperatures of 850 °C - 1250 °C the austenite grain coarsens significantly above a temperature of 1100 °C. Evaluation of recrystallization processes shows significant inhibition of dynamic and consequently postdynamic recrystallization after deformation of 60 % at temperature 850 °C. With increasing deformation temperature the contribution of dynamic and postdynamic recrystallization grows. Particles present in the microstructure evaluated by TEM are mostly M3C type. The optimization of material processing technology forged steel SA 508 for power supply applications has been evaluated and grain growth kinetics of precipitation processes in order to prevent undesirable coarse-grained structures.
