As a Surface Finishing Process:

• Removing surface contamination
• Creating a specific finish on a desired surface

As a Surface Preparation Process:

• Roughening surfaces for the application of paint
• Removing surface irregularities

As a Surface Modification Process, It Increases Compressive Stresses on the Surface:

• Providing increased fatigue life
• Decreasing susceptibility to stress corrosion
• Correcting distortion
• Forming structural steel and plate.
