Today, parallel to the rapid development of the industry, mechanical and metallurgical properties of the steel profiles that used as structural elements for constructions need to be improved. The constructions where steel profiles are used scaling up over time, require higher strength values for the materials or larger cross-sectional areas. Larger cross-sectional area has significant disadvantages in terms of product cost due to the weight increase, and the addition of strength-enhancing microalloys has significant disadvantages in terms of raw material cost. In this study, low-carbon and non-microalloyed base quality steel profiles that neither the hard nor the very soft material structure of undesirable were subjected to quenching of the profile surface to a certain depth with the quenching method, and then tempered the cooled surface by the region which was hot in the profile center. The changes in mechanical and metallurgical properties of the materials tested as a result of the process application designed according to the steel profile quality and cross-section. According to the results obtained, it was determined that the mechanical properties of the material increased and this increment was observed by the change in the material microstructure which was caused by the applied process. As a result of the study, it has been determined that more economical solutions can be revealed with the quenching process instead of using microalloying by using rare elements in a working environment where competition is gradually increasing.
