A Guide to Shot Blasting / Shot Peening
- Shot peening/shot blasting is a surface conditioning process which increases/improves a surface finish with benefits such as fatigue resistance.
- The process works by inducing residual stresses on the work piece surface to increase fatigue resistance.
- Shot blasting uses a peening chamber with the work item placed on a rotating turntable and bombarded with small balls at extremely high velocity.

- The only needed pack up is of the physical pellets.
Is shot peening and shot blasting process same?
This process is very different from Shot Blasting. Shot Blasting is used to either prepare or clean material, while shot peening is a procedure that is precisely controlled by a careful selection of media, along with the required concentration. It is a stressful process carried out on the surface of metals.

What material is used for shot blasting?
Types of metal abrasives used in shot blasting include steel grit, copper shots, and aluminum pellets. Other methods of shot blasting use silica sand, glass beads, synthetic materials like sodium bicarbonate (baking soda), and even agricultural materials like crushed kernels.

What is the difference between sandblasting and shot blasting?
One of the primary differences between shot-blasting and sandblasting is the medium used. Shot-blasting uses abrasive “shot” made of metal such as aluminum oxide or carbon grit almost exclusively. Sandblasting can use metallic shot, but more often it uses gentler abrasives such as organic media or glass.
Why shot blasting is done before painting?
The Benefits Of Blast Cleaning Blast cleaning helps in surface preparation by removing contaminants before coating, painting or lining. Surface cleaning removes rust and other contaminants which could cause problems with paint adhesion, or in the most extreme cases, compromise the integrity of the surface metal itself.

What is shot blast steel?
What Is Shot Blasting? Shot blasting is the process of abrading the surface of a metal workpiece to remove rust, dirt and other solidified contaminants by hurling a high speed stream of tiny pieces of stainless steel that resemble buckshot. It is capable of deburring, shaping and texturing a surface.
Is shot blasting easy?
Please note: While many tools exist that make the process easier, shot blasting is a delicate and potentially dangerous process. If undertaking the work, always ensure that physical safety is given a high degree of prominence as individual pieces of shot can be highly dangerous.

What is Shot Blasting?
Shot blasting is a mechanical cleaning process that uses spheres of material to remove oxides and other debris from the surface of another material . Although less commonly mentioned than sandblasting, shot blasting belongs in the same family of abrasive blasting processes in which sandblasting is categorized. The main difference between shot blasting and sandblasting is that shot blasting uses spherical shot as an abrasive media and a centrifugal wheel for propulsion, while sandblasting uses grains of sand and almost exclusively uses compressed air for propulsion.
How Does Shot Blasting Work?
Shot blasting works by propelling round materials known as shot media against a surface which in turn removes the contaminants of the surface and also can improve its finish. What type of shot media is used is a very important decision for the shot blasting process. The size and hardness of the shot material will dictate how much surface removal of the material being cleaned will occur. The type of material being cleaned will also play a role in the effectiveness of the shot blasting process. Typically, the shot material and size will be selected depending on the composition of the material whose surface is being shot blasted.
What is a shot blast recovery system?
The shot blast recovery system will collect the material shot that has already been propelled and impacted against the material being cleaned and return it to the propelling device to be used again. Shot blast recovery is typically performed through the use of a vacuum.
What is the difference between sandblasting and shot blasting?
The main difference between shot blasting and sandblasting is that shot blasting uses spherical shot as an abrasive media and a centrifugal wheel for propulsion, while sandblasting uses grains of sand and almost exclusively uses compressed air for propulsion.

Why blast zinc?
Since the outer layer of pure zinc requires very little impact or scouring to get required surface roughness, the blasting process should lightly roughen the surface without removing a major amount of the galvanized coating. The purpose of this procedure is to remove the oxide film from the zinc surface. Light sweep blasting can provide maximum topcoat adhesion over galvanizing.
