Influence of Annealing Temperature and Time on the Mechanical Properties of Selected Steels for Heavy Forgings

Original language description

Two types of steels used for production of heavy forgings were selected for the experimental evaluation. The effect of long time dwell at elevated temperatures and cooling during heat treatment on their mechanical properties was monitored in order to avoid the possibility of grain boundary embrittlement. Samples from evaluated steels 26NiCrMoV14-5 and 22CrNiMoWV8-8 were austenitized for 2 hours at temperature of 1200°C and oil quenched. Subsequently the annealing at temperatures (200 - 700)°C for 1 hourand 100 hours was applied. Selected mechanical properties, especially hardness and impact energy, were monitored. It was found that for steels 26NiCrMoV14-5 and 22CrMoNiWV8-8 exist the temperature intervals (300 - 400)°C and (500 - 600)°C respectively with the possible potential for toughness decreasing.
