With the continuous development of the metal manufacturing industry, stainless steel materials have found extensive applications in daily life, industrial manufacturing, and military fields. During the processing, fabrication, and use of stainless steel, its surface may exhibit uneven color spots or corrosion traces due to high-temperature oxidation, medium corrosion, etc. For aesthetic reasons or to address these issues, stainless steel pickling and passivation solutions are often employed for chemical cleaning and passivation treatment. This process forms a complete and uniform passive film on the surface, enhancing the material's aesthetics and corrosion resistance, and extending the lifespan of stainless steel.
Before using the stainless steel pickling and passivation solution on welded parts, the stainless steel surface needs to undergo degreasing, removal of dirt, and polishing. Then, pour the passivation solution into a plastic container and use it according to the material of the stainless steel and the severity of oxidation. Place the workpieces into the solution, typically at room temperature, and immerse them for 5-20 minutes or longer (specific time and temperature to be determined by the user based on their specific requirements). Remove the workpieces after complete removal of surface impurities, when the surface appears uniformly silver-white. After pickling and passivation, rinse the workpieces thoroughly with clean water and dry them.
