Abstract
The interrelation between the fine structure and the cold resistance of forgings and rolled sheets from ferritic-pearlitic steel 09G2SA-A after heat hardening and additional tempering at 450°C is studied. The additional medium-temperature tempering is shown to raise effectively the cold resistance of the steel due to coagulation and spheroidization of the cementite-type carbides, which make the structure of the steel more equilibrium.
