When processing various stainless steel plate products, the surface of stainless steel needs to be processed first. Affected by many factors, there may be some problems on its surface, such as weld defects and scratches. Poor polishing effect is also easy to cause poor stainless steel surface.
For stainless steel surface processing, serious weld defects are often encountered in stainless steel surface processing. Manual and mechanical grinding treatment is used to make up for the grinding marks, resulting in uneven surface and affecting the appearance. For the problem of inconsistent surface, only pickling and passivation is carried out for the weld, which also causes uneven surface and affects the appearance. Scratches are difficult to remove, overall pickling and passivation can not remove all kinds of scratches generated in the processing process, and can not remove carbon steel, spatter and other impurities adhered to the stainless steel surface due to scratches and welding spatter, resulting in chemical corrosion or electrochemical corrosion and rust in the presence of corrosive medium.
