Development and Production of KD Grade 3130 Steel for Sucker Rod

KD grade 3130 steel for sucker rod is new type steel for sucker rod took into account both the strength and corrosion resistance. According to the service conditions of product and the requirements of technology agreement, the chemical compositions of the steel and the production processes were designed. Through controlling the content of impurity elements such as S, P and H, control rolling and reasonable heat treatment process determined by experiments, Juneng Special Steel successfully developed KD grade 3130 steel for sucker rod. The product’s microstructure is uniform, the grain size is greater than 5 grade, all kinds of the non-metallic inclusions are less than 1.5 grade, the yield strength is greater than 795 MPa, the tensile strength is greater than 865 MPa, the tensile elongation is greater than 15%, the impacting energy is greater than 60 J. All kinds of the mechanical properties are in line with the user’s requirements.
