Key Advantages & Characteristics
-
Moderate Hardness & Excellent Toughness
Low carbon steel shot excels in ensuring cleaning efficiency while maximizing substrate protection, offering outstanding toughness and long service life. It effectively removes weld slag, rust, paint, and other contaminants without excessive cutting or embedding into softer base metals (e.g., mild steel, aluminum alloys), significantly reducing surface damage and stress concentration.
-
Superior Surface Peening Effect
Its moderate impact energy and high toughness make it an ideal medium for shot peening.
Introduces compressive stress: Through repeated impacts, it forms a beneficial compressive stress layer on the workpiece surface, significantly enhancing fatigue strength and stress corrosion resistance, thereby extending service life.
Uniform coverage: Its high resistance to breakage ensures process stability and even coverage.
-
Ideal Surface Roughness (Anchor Pattern)
The surface roughness (Anchor Pattern) generated by low carbon steel shot is smoother and more uniform compared to high carbon steel shot.
Enhances coating adhesion: This smooth and uniform anchor pattern provides an ideal base for subsequent spraying or coating, greatly improving adhesion and durability.
Excellent surface finish: The treated surface appears uniform without sharp peaks and valleys, making it suitable for workpieces requiring high aesthetic quality.
-
Ideal Surface Profile (Anchor Profile)
Its spherical shape creates a uniform and smooth surface profile, ideal for providing excellent coating adhesion.
-
Low Dust & Environmental Benefits
Its low breakage rate results in reduced dust generation during blasting operations.
Improves working environment: Reduces air pollution, promoting operator health.
Reduces equipment load: Lessens the burden on dust collection systems and extends the lifespan of consumables like filters.
-
Wide Application Range & Safety
Its gentle characteristics make it highly suitable for delicate workpieces prone to damage.
Broad material compatibility: Ideal for thin sheets, aluminum die-castings, stainless steel parts, precision castings, and other low-hardness metals or applications requiring substrate protection.
Avoids hydrogen embrittlement risk: Mechanical cleaning with low carbon steel shot eliminates the hydrogen embrittlement risk associated with acid pickling pre-treatments for plating high-strength steels.
Typical Applications
Surface Preparation
Cleaning and roughening metal surfaces before spraying, painting, or other coating processes to improve adhesion.
Shot Peening
Enhancing fatigue strength and stress corrosion resistance of metal parts by introducing compressive surface stresses.
Surface Cleaning
Removal of rust, scale, old coatings, and contaminants. Cleaning of castings, forgings, and welded parts.
Selection & Usage Guide
How to Choose the Right Size:
Heavy rust/aggressive cleaning: Larger sizes (e.g., S780/S660) for stronger impact.
General cleaning/descaling: Medium sizes (e.g., S550/S460) for balanced efficiency and coverage.
Fine cleaning/soft metals/peening: Smaller sizes (e.g., S330/S170) to protect substrates and ensure even coverage.
Complex shapes/internal surfaces: Smaller sizes to ensure media reachability.
Equipment Compatibility:
Suitable for most types of sandblasting and shot blasting equipment. Its high durability ensures relatively low wear on equipment.
Safety & Handling
Always wear appropriate Personal Protective Equipment (PPE), including safety goggles, gloves, respirators, and protective clothing.
Operate in well-ventilated areas or dedicated equipment.
