- The article presents results from determination of a grain size in microstructure of the 61SiCr7 (60C2A) spring steel. The material was selected with respect to the possibility of obtaining a nano-structured bainite without carbide precipitates. This was conducted basing on an influence of grain size on bainitic transformation time, microstructure and mechanical properties of the material type considered. The experiments indicated, that the addition of silicon caused difficulties related to revealing the grain boundaries of the austenite. Optimal parameters of heat treatment, which enable to reach the microstructure for observing grain sizes of the steel are shown. The growing grains of the tested steel was followed at five values of austenitizing temperature.
