A High Strength Hot Rolled Wear Resistant Steel And A Method Of Manufacturing Thereof
Abstract: The present disclosure discloses a method for producing high strength hot rolled wear resistant steel. The method starts with casting a steel ingot of desired composition, and then heating at first predetermined temperature for first predetermined time. Then the steel is subjected to forging in first cooling medium, and then reheated to second predetermined temperature for second predetermined time. After reheating, the steel is hot rolled at third predetermined temperature and subjected to rapid cooling in second cooling medium at fourth predetermined temperature. Then the cooled steel is soaked in second cooling medium at fourth predetermined temperature for third predetermined time, followed by cooling to room temperature in third cooling medium to obtain high strength hot rolled wear resistant steel. The steel manufactured by method primarily comprises pearlite and ferrite microstructure and exhibits tensile strength ranging from 750 MPa – 900 MPa and yield strength ranging from 450 MPa – 550 MPa
