Their strength and toughness may be at its maximum at cooling ratev_t=156℃ /min if 1.62% Si added, and may decrease due to precipitation of a host ofpro-eutectoid ferrite if Si>1.99% at v_t=7.9 and 0.9℃ / min. The peak value of strengthand toughness occurs while the Si content equal to 1.62 or 1.99% respectively. It is believedthat the best Si content is 1.62--1.99% for low carbon bainitic steels.
