Note: Isothermal transformation diagram for a steel with 0.39% C, 0.86% Mn, 0.72% Cr, and 0.97% Ni. The upper C-shaped curves describe transformation to pearlite; the lower C-shaped curves to bainite. Ferrite is not visible. The column on the right side of the figure indicates the hardness after completed transformation measured at room temperature.
