Abstract

In order to identify the best hot rolled steel producer for sucker rod manufacture, a research was performed in order to compare the mechanical strength and fatigue properties of sucker rods manufactured from steel bars delivered by two producers. The fatigue tests were performed on round test specimens on rotating bending and on full size sucker rod, using an axial fatigue test machine. The fatigue behaviors of both materials and sucker rods are practically the same.
