| Abstract: | The fracture of 45 steel rods during drawing was analysed by using SEM, EDS and metallography. The results showed that the metallurgical defects such as inclusions, coarse crystal grains and asymmetry of the grain size were the main reason resulting in fracture of the steel rods during drawing. |
