Product Introduction

S230, S280 and S330 steel shot are medium-size steel shot abrasives widely used for general shot blasting, casting cleaning and metal surface preparation.

Compared with fine steel shot sizes such as S70, S110 and S170, these grades provide stronger impact force and higher cleaning efficiency.

They are suitable for medium-sized castings, forgings, steel structures, machinery parts and metal workpieces that require effective removal of sand, rust, scale and surface impurities.

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

 

1. Stronger Cleaning Power

S230, S280 and S330 steel shot provide higher impact force than smaller steel shot sizes.

They can effectively remove:

  • Sand residues
  • Rust
  • Oxide scale
  • Surface contaminants
  • Old coating or paint residues

These grades are suitable for workpieces that require stronger cleaning performance.

 

2. Good Balance Between Efficiency and Surface Quality

These medium-size steel shot grades offer a good balance between cleaning efficiency and surface finish.

They can improve blasting speed while helping maintain a relatively uniform surface profile.

This makes them suitable for many standard industrial shot blasting processes.

 

3. Stable Blasting Performance

With controlled hardness, consistent particle size and stable chemical composition, S230, S280 and S330 steel shot can provide reliable performance during continuous blasting operation.

They help customers achieve consistent cleaning results and stable surface preparation quality.

 

4. Good Durability and Recyclability

S230, S280 and S330 steel shot have good toughness and wear resistance.

During repeated blasting cycles, they can help reduce:

  • Abrasive breakage
  • Dust generation
  • Excessive media consumption
  • Unstable blasting performance

This supports better cost control in daily production.

 

5. Flexible Size Selection

Different sizes can be selected according to the workpiece size, surface condition and required cleaning strength.

Steel Shot Size Main Feature Recommended Use
S230 Steel Shot Medium-fine size, balanced cleaning Medium castings, forgings, general cleaning
S280 Steel Shot Higher impact force, efficient cleaning Castings, steel parts, rust and scale removal
S330 Steel Shot Stronger impact, deeper cleaning effect Larger castings, steel structures, heavy surface cleaning

Size Application Guide

S230 Steel Shot

S230 steel shot is suitable for medium cleaning strength and general surface preparation.

It is commonly used for medium-sized castings, small steel structures, forgings and metal parts that require stable cleaning performance without excessive surface roughness.

S280 Steel Shot

S280 steel shot provides stronger impact force and higher cleaning efficiency than S230.

It is recommended for removing rust, scale, sand residues and surface impurities from castings, steel parts and machinery components.

S330 Steel Shot

S330 steel shot offers a stronger cleaning effect and is suitable for heavier surface cleaning applications.

It is commonly used for larger castings, steel structures, thick steel parts and workpieces with heavier rust, scale or surface contamination.
