1. Preservation of Stainless Properties: The primary feature of stainless steel is its resistance to corrosion. However, in some cases, stains, dirt, or corrosion may develop on the surface. Sandblasting removes such contaminants and restores the stainless properties.

2. Surface Smoothing: Sandblasting helps to eliminate rough or irregular surfaces on stainless steel. This is important for achieving an aesthetic appearance or reducing surface roughness.

3. Surface Cleaning: Over time, stainless steel surfaces can accumulate dirt, grease, and other contaminants. Sandblasting cleans these pollutants and residues, ensuring a clean and hygienic surface.

4. Preparation for Painting or Coating: Stainless steel surfaces can be prepared for painting or coating through sandblasting. A smooth surface aids in better adhesion of paint or coating.

5. Surface Dulling: In some applications, reducing shine or dulling the surface may be desired.
Sandblasting can be used to achieve a matte finish.

6. Rust and Corrosion Prevention: Sandblasting can be applied to prevent or reduce rust and corrosion on the surfaces of stainless steel.

Sandblasting is a commonly used process to improve the surface quality and preserve the properties of stainless steel. Therefore, it is frequently preferred for maintenance and preparation of stainless steel in various industries, including industrial, automotive, marine, food processing, and many others.
