The invention discloses superaustenitic stainless steel based on the synergistic effect of Mo and N and a preparation method of the superaustenitic stainless steel, and belongs to the technical field of high-performance metal materials. The stainless steel comprises the following components in percentage by mass: 26.0%-26.5% of Cr, 3.48%-4.52% of Mo, 0.29%-0.51% of N, 23.0%-25.0% of Ni, less than or equal to 0.01% of C, 0.40%-0.65% of Mn and the balance of Fe and inevitable impurities. According to the method, on the premise that the PREN value is kept basically unchanged, the point corrosion resistance of the stainless steel in a chloride ion-containing medium is remarkably improved by synergistically reducing the Mo content and increasing the N content and utilizing the interaction effect of Mo and N. The synergistic effect is embodied in inhibiting pitting initiation, slowing down pitting extension, promoting repassivation and forming a more protective passive film structure. The material is especially suitable for harsh corrosive environments such as offshore oil and gas exploitation and seawater desalination.
