1 Cleaning and polishing: If there is damage, it should be polished, especially the scratches and splashes caused by contact with carbon steel parts, and the damage caused by cutting slag must be carefully and thoroughly cleaned and polished.

2 Mechanical polishing: Polishing with appropriate polishing tools requires uniform processing and avoids over-polishing and re-scratching.

3 Degreasing and dedusting: Before the pickling and passivation of stainless steel parts, the oil, scale, dust and other debris must be removed according to the process.

4 Water blasting treatment: According to different processing requirements, different micro glass beads, different process parameters, and overspray should be avoided.

5 Pickling passivation: The pickling passivation of stainless steel parts must be passivated strictly according to the process requirements.

6 Cleaning and drying: After pickling and passivation, it should be neutralized, rinsed and dried according to the process, and the residual acid solution should be completely removed.

7 Protection: After the surface treatment of stainless steel parts is finished, it should be protected to avoid secondary pollution caused by personnel touch and oil, dust and other debris.
