Product Introduction

Fine Steel Shot for Precision Cleaning and Surface Preparation

S70, S110 and S170 steel shot are fine-size steel shot abrasives used for precision cleaning, light shot blasting and controlled surface preparation.

Compared with larger steel shot, these small-size steel shot grades provide:

 
Better surface coverage
 
Smoother blasting results
 
Lower impact on thin or delicate workpieces
 
More uniform surface finish

They are suitable for small castings, aluminum parts, zinc alloy parts, precision components and thin metal workpieces.

Manufacturing Process

Our steel shot is produced through melting, atomization, screening, heat treatment and quality inspection. The molten steel is atomized into spherical particles, then processed through controlled quenching and tempering to obtain suitable hardness, toughness and microstructure.

After heat treatment, the steel shot is screened into different sizes and tested for chemical composition, hardness, density, particle size distribution and internal defects. This process ensures consistent blasting performance and reliable batch quality for continuous production lines.

Advantages

Zhongxing steel shot offers strong cleaning efficiency, good durability and stable surface treatment results. Its rounded shape makes it suitable for removing sand, scale, rust and surface contaminants while reducing excessive cutting on the workpiece.

The product features stable hardness, controlled carbon and manganese content, good density and reliable impact resistance. It can help improve blasting productivity, reduce abrasive consumption and support consistent surface roughness in industrial shot blasting systems.

Advantages of S70, S110 and S170 Steel Shot

 

1. Fine Particle Size and Better Coverage

S70, S110 and S170 steel shot have smaller particle sizes, allowing them to reach narrow corners, complex shapes and detailed surfaces more effectively.

They are especially suitable for small parts and workpieces with complicated structures.

 

2. Smooth and Uniform Surface Finish

These fine steel shot sizes help achieve a cleaner, smoother and more uniform surface.

They are recommended for applications where excessive roughness or strong impact should be avoided.

 

3. Stable Blasting Performance

With consistent particle size and controlled hardness, S70, S110 and S170 steel shot provide stable blasting performance during continuous operation.

They help customers maintain consistent cleaning results in different shot blasting processes.

 

4. Lower Abrasive Consumption

Good toughness and wear resistance help reduce breakage and dust generation.

This can lower abrasive consumption and improve overall blasting cost control.

 

5. Flexible Size Selection

Different sizes can be selected according to the required cleaning effect:

Steel Shot Size Main Feature Recommended Use
S70 Steel Shot Very fine size, smooth finish Precision cleaning, thin workpieces, small parts
S110 Steel Shot Balanced cleaning and surface protection Small and medium castings, general surface cleaning
S170 Steel Shot Stronger impact and higher efficiency Castings, steel parts, light rust and scale removal
