In this study, the impact of titanium (Ti) on low-alloy steel alloys is examined, focusing on the mechanical properties of the alloy with varying Ti content levels. Heat treatment was conducted to enhance the mechanical properties and performance indicators of the casting samples. The elemental volume distribution mapping and microstructure analysis of the research samples were performed using SEM - Carl Zeiss Ultra Plus Field Emission. Subsequently, the hardness and wear resistance characteristics of samples containing Ti contents of 0, 0.1, 0.3, 0.5, 0.8, and 1.1 were evaluated post heat treatment. Notably, steel samples containing 0.3% and 0.5% Ti, exhibiting structures of ferrite, martensite, and limited bainite, demonstrated superior hardness and wear resistance properties. Abrasive wear resistance tests were conducted using a specialized device with a horizontal diamond disc. The primary objective of this research is to introduce the developed technology for the rolling mill rolls at a prominent metal manufacturing enterprise in the republic, resulting in enhanced economic efficiency through increased production volume. Consequently, achieving a hardness of HB 323 and improving wear resistance by 1.2 times were notable outcomes of the study.
