Abstract

Abstract. Purpose. Study of the influence of  technological factors and  macrostructure of centrifugally-cast billets from steel 40H25N20С2 on the mechanilal properties under different temperatures. Methodology.  Macrostructure of pipe  castings from steel 40H25N20С2 produced by horizontal centrifugal casting machines was analyzed. The influence of parameters of centrifugal casting on the character of macrostructure was investigatedMmechanical tests under  different temperatures were carried out. Findings. It was shown the influence of parameters of centrifugal casting and dendritic macrostructure of pipe castings from steel 40H25N20С2 on the mechanilal properties. It was fixed that more propitious is the dispersed transcrystalline  macrostructure of pipe castings. The parameters of centrifugal casting ensuring formation of dispersed transcrystalline  macrostructure of pipe castings were determined. It was shown the influence of  parameters of centrifugal casting and macrostructure on the mechanical properties of pipe castings under different temperatures. Originality. We discuss the processes of macrostructure formation of  pipe  castings from steel 40H25N20С2 under different conditions of centrifugal casting and their influence on the mechanilal properties. Practical value. The obtained results allow to produce centrifugal castings from steel 40H25N20С2 with raise mechanical and service properties.
