Process method for improving corrosion resistance of 00Cr17Ni14Mo2 material

The invention discloses a process method for improving the corrosion resistance of a 00Cr17Ni14Mo2 material, which comprises the following steps: carrying out oil removal treatment on a part to remove pollutants on the surface of the part; cleaning the surface of the part by using room-temperature flowing water; the surface of the part is coated with THIF-125 passivation paste at the room temperature for corrosion resistance treatment; the surface of the part subjected to corrosion-resistant treatment is cleaned; pH value detection: detecting whether the surface of the part is qualified or not; deionized water is adopted for cleaning the surface of the part; and the part is dried, and a corrosion-resistant film layer is formed on the surface of the part after drying is completed. A series of treatment is carried out on the pipe part, THIF-125 passivation paste is smeared on the surface of the part for corrosion resistance treatment, and a corrosion-resistant film layer with a protection effect is formed on th
