What factors affect the recycle times of steel shot & steel grit

Materials and Quality

Material: Different materials (cast steel, stainless steel, alloy steel) have different durability. Stainless steel is corrosion-resistant, while cast steel is cost-effective but easily damaged.

Hardness and Density: Steel shot with moderate hardness (too hard and it's brittle, too soft and it wears quickly) and high density has a longer lifespan, can withstand high impacts, and is less prone to breakage.

Internal Defects: Porosity, cracks, and shrinkage cavities significantly reduce lifespan.

Production Process

Heat Treatment: Good quenching and tempering processes are key to ensuring uniform hardness and wear resistance of the steel shot.

Forming Control: Ensure consistent dimensions and good sphericity to reduce the loss of irregular shot.

Operating Environment

Cleanliness: The cleanliness of the processing environment and the absence of impurities.

Humidity: Humid environments easily cause rust (especially in low-carbon steel), affecting its physical properties and lifespan.

Corrosivity: Chemical media accelerate corrosion; stainless steel shot has an advantage in this environment.

Operation and Use:

Hardness Matching: The hardness of the steel shot should match the hardness and surface roughness of the workpiece to be cleaned. Excessive hardness will accelerate its own wear.

Usage Frequency: Higher shot blasting/peening frequency naturally leads to faster wear.

Operating Techniques: Correct equipment parameters (air speed, blasting angle) can reduce abnormal wear.

Summary: High-quality, high-density steel shot/grit without internal defects, under suitable hardness and environment, combined with proper operation, can achieve the longest recycle times.
