✦ Synopsis

Control-rolled and normalized C-Mn steels with and without boron alloying at two finish rolling temperatures of 800 ~ and 1 000 ~ were studied with respect to their tensile properties in order to investigate the role of boron in enhancing the strength of these materials. It was found that in boron steels ultimate tensile strength increased and impact transition temperature decreased owing to a decrease in grain size and an increase in pearlite fraction at both the finish rolling temperatures.
