In the article examined dependence of grain growth from soak time and temperature. It is researched influence of an initial grain size on stress-strain curves behaviour of steel C45, discussed the significance of this parameter in creation of prediction models of hot forming processes. Obtained stress-strain curves were used to calculate critical strain and define coefficients of relation between initial grain size and critical strain.
