The invention discloses high-strength corrosion-resistant steel. The steel comprises the following chemical ingredients in percentage by mass: smaller than or qual to 0.09% of C, smaller than or equal to 0.40% of Si, 0.80% to 0.90% of Mn, 0.090% to 0.10% of P, smaller than or equal to 0.005% of S, 0.02% to 0.06% of Al, 0.52% to 0.58% of Cu, 0.42% to 0.48% of Ni, 0.030% to 0.050% of Ti, and the balance of Fe and inevitable impurities. A production method of the steel comprises the following steps: performing hot metal pretreatment; smelting in a rotary furnace; performing LF refining; performing continuous casting; and performing a hot rolling process. A steel product produced by adopting the method is excellent in performances and low in cost.
