In today's society, stainless steel products are generally polished during the production process, and only a few products such as water heaters, water dispenser liners, etc. do not need to be polished. Therefore, this requires a good polishing performance of the raw material. The main factors affecting the polishing performance are as follows:
1. Raw material surface defects. Such as scratches, pitting, soaking and so on.
2. Raw material problems. The hardness is too low, it is not easy to be polished when polishing (BQ is not good), and the hardness is too low, and the surface is prone to orange peel phenomenon during deep drawing, thereby affecting BQ property. The BQ with high hardness is relatively good.
3. After deep drawing, the surface of the area with a large deformation will also have small black spots and RIDGING, thus affecting BQ.
