Abstract
The application of microalloying, controlled rolling and controlled cooling has been the most important achievements in the metallurgical industry in the last 30 years. Microstructure and mechanical properties of steels are g reatly improved by applying these technologies. This application resulted i n significant progress in the production and application of high-strength l ow-alloy steel. In the present investigation, the effect of different lolli ng schedules on the microstructure and mechanical properties of grade X60 A PI steel has been studied. The tensile and impact properties of this steel are related to the microstructure introduced by various rolling schedules. It has been found that it is possible to obtain a steel with 25 % elongatio n to fracture, 560 MPa yield strength, 650 MPa tensile strength, and an imp act transition temperature of -35 degreesC through thermomechanical rolling process.
