Abstract	This study delves into the impacts of step cooling on the microstructure and mechanical attributes of carbon steel. Step cooling, a methodical heat treatment process comprising sequential cooling phases, was administered to samples of carbon steel. Through optical microscopy, the evolution of microstructure, encompassing phase alterations and grain structure, was scrutinized. Mechanical traits, including hardness, tensile strength, were assessed via standardized tests, coupled with fractural structural analysis. The findings suggest that step cooling markedly affects microstructural refinement, modifying the distribution of present phases. Furthermore, discernible variations in mechanical properties were noted, revealing enhanced strength and toughness qualities in the step-cooled specimens when juxtaposed with those conventionally cooled. This investigation unveils valuable insights into the potential advantages of step cooling as a viable approach for augmenting the properties of carbon steel, thereby presenting avenues for optimizing its utilization in industrial settings.
