The invention relates to a high-strength high-carbon steel material for pump bearings, which contains the following chemical components in percentage by mass: 1.2-1.4% of carbon, 0.7-0.9% of silicon, 0.8-1.1% of manganese, 2.3-2.5% of chromium, 0.4-0.7% of vanadium, 0.1-0.2% of molybdenum, 0.04-0.06% of niobium, 0.02-0.04% of Pr, at most 0.04% of S, at most 0.04% of P and the balance of iron. By adding the vanadium, niobium, molybdenum and other elements on the basis of high-carbon steel, the obtained alloy steel has the advantages of high hardness, favorable impact resistantce, favorable wear resistance, favorable toughness, high corrosion resistance and high temperature resistance, is suitable for pump bearings and other load-bearing high-abrasion parts, and can not be easily damaged. Part of scrap iron is used as the raw material, and secondary refining is performed, so that the product quality is more stable and uniform. When the refining agent is used for casting production, the yield is obviously enhanced, the porosity in the casting is lowered by 1-2 degrees, and the oxide inclusion content is obviously lowered by 2 levels or so.
