Abstract
Construction steels must have many mechanical properties according to standards. One of these is suitable impact resistance feature. In the research, the impact transition temperatures of the construction steels produced from scrap in Türkiye as B500B-00, B500C-00, GR60T-01, GR60T-BR, GR60T-02 standards were determined in the range of +60/−30 °C temperatures. The microstructures of the samples were observed by scanning electron microscopy, X-ray diffraction. Tensile and microhardness tests were performed on the samples. Fracture surfaces of samples were examined by using SEM. The Charpy fracture energies of five different quality construction steels were detected between 76 and 105 J at 60 °C and 14–22 J at −30 °C. Izod fracture energies were measured between 100 and 135 J at 60 °C and between 35 and 48 J at −30 °C. The impact transition temperatures of the samples were determined in the range of 35 °C to −5 °C.
