Plating after deplating. Stainless steel is rarely colored by electroplating. Most of them are sprayed or sprayed. Workpieces with high requirements for electroplating and coloring can only be recolored after deplating with strong acid. Workpieces with low requirements for electroplating and coloring, which are not seriously discolored, can be sprayed with canned electroplating, but the appropriate color code should be selected to avoid obvious spray marks.

Therefore, after the stainless steel workpiece becomes discolored, corresponding remedial measures should be taken according to the specific requirements of the workpiece.
