The invention discloses a high-strength anti-corrosive steel product. The high-strength anti-corrosive steel product comprises the following components in percentages by weight: less than 0.02% of carbon, less than 0.5% of silicon, 0.4-0.6% of manganese, less than or equal to 0.015% of phosphorus, less than or equal to 0.01% of sulfur, 9.5-10.5% of chromium, 0.35-0.5% of nickel, 0.2-0.35% of molybdenum, less than or equal to 0.65% of copper, less than or equal to 0.007% of aluminum, less than or equal to 0.15% of titanium, less than or equal to 0.04% of vanadium, less than or equal to 0.12% of niobium, less than or equal to 0.02% of zinc, less than or equal to 0.07% of tungsten, less than or equal to 0.03% of cobalt, less than or equal to 0.04% of tin, less than or equal to 0.02% of lead and the balance of ferrum. The high-strength anti-corrosive steel product disclosed by the invention has the beneficial effects that the content of carbon and sulfur is reduced, the steel tissues are refined, and the molecular structural density of the steel is improved to achieve corrosion resistance and mechanical property; as the tissues of the steel are full, the diffusing speed of steel atoms is increased, chromium in the crystals and in the crystal boundary in a metallographic structure is easy to balance, thereby playing a role of preventing crystal boundary corrosion. Meanwhile, spot corrosion is replaced by uniform tiny corrosion on an integral plane, so that the corrosion rate is delayed; alloys such as molybdenum, nickel and copper alloys are added to form an intermetallic compound, so that the matrix structure is strengthened; crystalline grains can be refined by adding niobium, vanadium and titanium, so that the toughness of a material is further improved.
