After grinding out surface defects on stainless steel, the traces left by acid washing and passivation are still very visible, giving the surface an unsightly appearance. What can be done? If surface defects such as scratches occur after pickling and passivation, how should these defects be repaired?
On a regular stainless steel surface, the effects of grinding are quite noticeable, unless the original surface was already polished and the ground surface is also polished in the same way. To avoid obvious marks on the surface after grinding, a full-scale sandblasting treatment can be used.
The surface polishing technology for stainless steel is highly mature; polishing is all that is required. For example: All medical devices are polished.
