Stainless Steel Surface Treatment
1. Cleaning and polishing: If there is damage, it should be polished, especially scratches and splashes caused by contact with carbon steel parts, and damage caused by cutting slag must be carefully and thoroughly cleaned and polished.
2. Mechanical polishing: Use appropriate polishing tools for polishing, requiring uniform treatment, and avoid over-polishing and re-scratching.
3. Degreasing and dust removal: Before pickling and passivation of stainless steel parts, oil, oxide scale, dust and other debris must be removed according to the process.
4. Water blasting treatment: According to different treatment requirements, choose different micro glass beads, different process parameters, and avoid overspray.
5. Pickling passivation: The pickling passivation of stainless steel parts must be passivated in strict accordance with the process requirements.
6. Washing and drying: After pickling passivation, neutralization, washing and drying should be carried out strictly according to the process to thoroughly remove the residual acid.
7. Protection: After the surface treatment of stainless steel parts is completed, protection should be done to avoid secondary pollution from touching by personnel, oil, dust and other sundries.
8. Avoid reprocessing: After finishing the surface treatment of stainless steel parts, avoid reprocessing the parts or products.
