The article deals with non-destructive measuring and evaluation of residual stresses and chemical properties of stainless steel sample and its possibility to affect functional properties of the material. X-ray diffractometry can accurately determine values of both residual stress and austenite percentage. Due that this method of measuring is non-destructive, it is possible to ensure measure repeatability and measured component is able to keep its original function. Monitoring of residual stresses in components can be useful in predicting damage incidences due to workload over lifetime of components and together with austenite volume it can also be used as evaluation parameter of suitability of applied manufacturing technological operations.

Keywords: Residual stress, austenite volume, stainless steel, X-ray diffraction
