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.

Productivity is the relationship between the output produced by a production or service system and the input used to create this output. High efficiency is to produce more with the same amount of resources or more output with the same input. However, it is accepted that efficiency and working life quality are closely linked. The efficiency of the enterprises is important for the society and the country in which they carry out their activities as well as for themselves. While the productivity of the enterprises is reflected in the decrease in the costs, increase in the profit, the efficiency of the enterprises has reflections on the new investments, increased added value, the welfare of the society and employment in terms of society and country. It is also important to measure the efficiency that is so important in order to make it sustainable in enterprises. The productivity measured continuously in enterprises will enable managers to make correct and rational decisions, to see problems on time and to produce solutions. The purpose of this study is to determine the factors affecting the productivity of the employees in the steel industry. The study was examined under five titles. These are: “Demoraphic Information”, “Economic Factors”, “Physical and Ergonomic Factors”, “Psycho- Social Factors” and “Risk Factors”. According to the findings of the study, the effect of factors on the employees will be determined and improved findings will be presented to the management of the enterprise.
