The difference between Passivation Of Stainless Steel and stainless steel pickling passivation

Although Passivation Of Stainless Steel  treatment and stainless steel pickling passivation can improve the rust and oxidation resistance of the workpiece, there are still some differences between the two treatment processes, mainly because the stainless steel pickling passivation is pickled and blunt. Two-in-one, with the effect of degreasing and rust removal.


In order to improve the anti-rust ability of stainless steel, it is necessary to do the passivation treatment of stainless steel. When the passivation treatment is required, the surface of the workpiece must be clean, and there must be no oil, scale, solder spots and rust, so it needs to be cleaned before passivation. Degreasing is generally treated with a stainless steel cleaner or a neutral degreaser.


In order to simplify the operation steps, the stainless steel pickling passivation solution can be used, and the cleaning and passivation can be combined in one step. Stainless steel pickling passivation can remove oxide scales, solder spots, etc. produced after welding and high-temperature processing, so that the silver is bright and bright, and the treated surface forms an oxide film with chromium as the main substance, no longer Secondary oxidation is generated to achieve the purpose of passivation, thereby improving the surface anti-corrosion quality of stainless steel products and prolonging the service life of the equipment.


In general, for stainless steel workpieces with relatively low salt spray requirements, we can directly do stainless steel pickling passivation treatment, rust and rust prevention in one step, the process is simple and environmentally friendly. For workpieces with high salt spray requirements, it is recommended to separate the cleaning and passivation treatments because thePassivation Of Stainless Steel  solution is better than the stainless steel pickling passivation solution.
