A PROCESS TO PRODUCE UNDER PARAEQUIL-IBRIUM CONDITION A FULLY PEARLITIC MICROSTRUCTURE IN HYPOEUTECTOID STEEL

摘要

The invention relates to a process under paraequilibrium condition to produce a fully pearlitic microstructure (98%) in hypoeutectoid steel, the other alloying elements such as herein described remaining fixed, the fully pearlitic microstructure is developed under minimum 0.35 wt% carbon without any isothermal holding treatment, and in that an elongation value of minimum 8% with a tensile strength of minimum 850 MPa, is achieved for the developed Steel grade. {Figure 4}
