Sandblasting introduces residual stress and contamination risks, requiring subsequent passivation treatment.

Sandblasting can produce a uniform matte surface, but it will:

1) Introduce surface residual compressive stress (generally beneficial for fatigue, but may affect deformation of thin sheets).
2) Use of iron-containing abrasives will cause iron contamination, leading to rust spots.
3) Destroy the original passivation film, reducing corrosion resistance.

Recommendations: Use dedicated stainless steel abrasives or glass beads, and perform acid pickling and passivation after sandblasting to restore the passivation film; avoid sandblasting in hygienic applications, and instead use shot peening + electrolytic polishing.
