Today's society in the production of stainless steel products generally have been polished this process, only a small number of products such as water heaters, drinking fountains, etc. do not need polishing. Therefore, the polishing performance of the raw material is required to be good. Polishing performance of the factors that affect the following points:
① raw surface defects. Such as scratches, pitting, acid pickling.
② raw material problems. Hardness is too low, polishing is not easy to throw bright (BQ is not good), and hardness is too low, in the deep drawing surface prone to orange peel phenomenon, thus affecting the BQ. BQ hardness is relatively high.
③ After deep drawing products, the deformation of the surface area will be a great little black spots and RIDGING, thus affecting the BQ.
