Summary:Manufacturing methods and the applied heat treatment are important for the properties of materials. Building safe constructions with the materials used depends on the knowledge and correct use of their properties. In this study, cold drawn bar specimens of Ç1040 are heat treated in three different temperatures (500 o C, 650 o C, 840 o C) and the strength, hardness, and strain values are compared with those of untreated materials. Cold drawn bars has shown higher strength values when compared with the hot rolled bars. This is because of the type of process selected for manufacturing. By heat treatment, strain has increased, hardness and strength have decreased. It has been observed that the rate of increasing or decreasing depends on the temperature and duration of the heat treatment.
