Abstract The metallurgical structure of the specimens with higher strength is detected by optical microscope, and there is more than 50% pseudo-eutectoid pearlite in the specimens, resulting in an effect of remarkable pearlite strengthening. Conclusion of comparative analysis of different process is that far more than balance content of pseudo-eutectoid pearlite can be gotten by inhibiting proeutectoid ferrite transformation and making final cooling temperature lower than the [Ar1] of air cooling. The factors influencing the proeutectoid ferrite transformation during laminar cooling are discussed in this study.
