Nowadays, it is very important to monitor the quality of engineered products. An indispensable part of the product’s qualitative characteristics is the integrity of the surface. It also includes a residual stress monitoring area. Residual stresses can be detected and measured by many destructive and non-destructive methods. The implementation of non-destructive methods is becoming increasingly desirable because the component being tested can be checked without disturbing and therefore continue to be used. The eddy currents method is expanded in the engineering practice to detect cracks in conductive materials. Residual stress detection has the potential in the future to accelerate and reduce the detection of residual stresses directly in the production process. Presented article is aimed at comparing the response of the eddy currents to the residual stresses induced in the steel material. Experiments were performed on free cutting steel 11SMnPb37. Residual stresses were induced by chip machining. Subsequent were investigated different residual stresses values in response to the eddy currents. The results of the experiment point to the possible application of the eddy current method to detect residual stresses in conductive materials.
