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?
If permitted, the surface should be sandblasted
