The Effects of Stainless Steel Pickling Paste Used on the Surface of Stainless Steel

In fact,it forms a very dense, well-covered and firmly adsorbed film on the surface of stainless steel in the process of pickling and passivation.The passivation film can prolong the rusting time of the stainless steel and effectively protect the surface of the stainless steel, which makes the stainless steel more corrosion resistant.

 

It can be seen that stainless steel pickling paste has an important role in improving the surface quality and performance of stainless steel materials.And it will not have any effect on the metal surface after the passivation treatment.Neither the appearance of the stainless steel nor the hardness of the stainless steel will change significantly.

 

Stainless steel pickling paste can be used in all stainless steel products of SUS300 series.The corrosion resistance of stainless steel workpiece can be greatly improved after treatment.And it can improve the thermodynamic stability of stainless steel in environmental media.Passivated stainless steel in a more positive position in the metal potential sequence.It is similar to precious metal, has stable chemical property;The unpassivated stainless steel is in an activated state and more negative potential.It is similar to ordinary steel.

 

Not only that, after the pickling and passivation treatment, the surface has enough cleanliness.Especially the pickling effect can remove layer of metal pollutants on the surface of stainless steel, and embedding the impurities of stainless steel, such as copper zinc cadmium, lead, and low melting metal free iron.It makes the surface of chromium nickel enriched and stable.The pollution of these metals can easily lead to corrosion damage of stainless steel.

 

In practical application, stainless steel pickling passivation is generally used as a post-treatment, especially for stainless steel pretreatment.It is mainly to clean the stainless steel workpiece,apply the pickling paste on the stainless steel after improving the surface condition of the stainless steel.http://www.hdpicklingpassivation.com/
