Polishing property of stainless steel

In today's society, stainless steel products are generally polished in the production process, only a few products such as water heaters, water dispensers, etc., do not need polishing. Therefore, this requires that the polishing properties of raw materials are very good. The main factors that affect the polishing performance are as follows:
① Surface defects of raw materials. Such as scratches, pitting, pickling, etc.
② Raw material problem. The hardness is too low, and it is not easy to polish when polishing (BQ is not good), and the hardness is too low, and the orange peel phenomenon is easy to appear on the surface when the deep drawing, thus affecting the BQ property. BQ with high hardness is relatively good.
③ After deep stretching of the product, the surface of the area with great deformation will also produce small black spots and RIDGING, thus affecting the BQ property.
