Note: Comparison of continuous cooling transformation (CCT) diagrams for two steels. (a) 1038 steel (0.38 C, 0.20 Si, 0.70 Mn, 0.020 P, 0.020 S) rolled, austenitized at 860 °C (1580 °F), with as-quenched austenite grain size of 8 to 10. (b) Alloy steel (0.35 C, 0.28 Mo, 1.55 Mn, 0.20 Si, 0.025 P, 0.025 S) rolled, austenitized at 845 °C (1555 °F), with as-quenched austenite grain size of 7 to 8.
