In recent years practical and scientific interest in investigating segregation processes to assess the mechanism of steel embrittlement by impurity elements has grown. This interest was noticeably stimulated by industrial use of new metallurgical technologies that ensure higher purity of steel with respect to impurity elements. It has become possible to decrease the content of expensive molybdenum due to the higher purity of steels without substantial change in their properties. In the present work the structure and properties of steel 30KhNMA with conventional and elevated purities, standard and reduced concentrations of molybdenum, and microadditions of V, Ti, and Nb are investigated.
