The invention relates to super-strength sucker rod steel which is characterized by comprising the following chemical components in percentage by weight: 0.23-0.46 percent of carbon (C), 0.1-0.3 percent of silicon (Si), 1.25-1.55 percent of manganese (Mn), less than 0.02 percent of phosphorus (P), less than 0.015 percent of sulphur (S), 0.05-0.15 percent of vanadium (V), 0.025-0.032 percent of chromium (Cr), 0.05-0.13 percent of rare earth (Re) and the balance of iron (Fe), wherein the rare earth is a mixture of lanthanum (La) and cerium (Ce). The invention has the advantages of high comprehensive mechanical property, overall consistent corrosion resistance, super strength and anti-corrosion, breaks the limits of technical means of shot blasting strengthening or electroplating chemical treatment, and the like to the strengthening or the anti-corrosion of the sucker rod and is a brand-new low-cost sucker rod material.
