Products used in the construction of machines and shipbuilding as well as petrochemical industry, such as shafts, bars, pipes and the like from two-phase stainless steel are currently very popular. It is required that they meet certain quality criteria. They must be characterized by suitable properties of the surface layer to meet the requirements of potential buyers. In the article impact of processing parameters on the degree of relative strain hardening and index of surface roughness reduction were presented. The burnishing process was carried out for two-phase stainless steel. Burnishing process of the shafts neck was performed using burnisher roller. The experimental research were obtained in the surface layer increase in hardness and the material ratio curve a convex shaped, which, taking into account the load capacity of the surface will be directly affected by its resistance to wear and corrosion. The experimental research by application of the burnishing process was made in the Laboratory of Production Engineering. After the studies it was found that the hardness of the surface layer and the roughness of the shaft necks an important influenced by technological parameters of processing (burnishing speed, feed rate and depth of burnishing). The objective of applying burnishing process may be, for example, the need to increase surface smoothness and dimensional accuracy of part.
