High Strength Pearlitic Steel And A Method Of Manufacturing Thereof

Abstract: ABSTRACT TITLE: “HIGH-STRENGTH PEARLITIC STEEL AND A METHOD OF MANUFACTURING THEREOF” The present invention discloses a method for producing high strength pearlitic steel which is processed very fast (fast processing). The method starts with casting a steel ingot of desired composition, and then heating at first predetermined temperature. Then the steel is subjected to forging in first cooling medium, and then reheated to second predetermined temperature. 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 pearlitic steel. The steel manufactured by method primarily comprises pearlite and ferrite microstructure and exhibits tensile strength ranging from 550 MPa – 860 MPa and yield strength ranging from 310 MPa – 550 MPa with ductility of 25% - 40%.
