Steel Grit
Steel grit is produced by crushing steel shot into angular particles. Its sharp edges provide excellent cleaning efficie
Product Description
Applications
Core Technical Advantages
Secondary Quenching Process
After primary centrifugal quenching, we apply a second hardening cycle. This creates a denser microstructure, significantly inhibiting carbon deviation. The result: 1.3× longer service life, lower breakage rate, less dust, better elasticity and faster cleaning speed.
Cost Efficiency
Thanks to secondary quenching, our steel grit delivers 30% longer operational life than conventional cast grit. For high-volume blasting operations, this translates directly into lower media consumption, reduced downtime and significant total cost savings.
Manufacturing Process
8-step controlled production — from raw steel to finished abrasive media, every stage is engineered for consistency.
Smelting
Electric Arc Furnace
Adjust steel composition to reduce harmful sulfur and phosphorus content.
Refining
Ladle Refining
Further purify molten steel to ensure superior material quality.
Granulation
Centrifugal Casting
High-speed centrifugal forming controls shape quality and minimizes physical defects.
Selection
Defect Separation
Remove hollow or deformed particles to improve shot density and uniformity.
Quenching
Secondary Hardening
Double quenching refines grain structure, enhancing toughness and inhibiting carbon deviation.
Tempering
Precision Heat Treatment
Precise temperature and time control achieve optimal hardness uniformity across batches.
Crushing
Grit Production
Unique crushing process improves grit fullness and angularity while minimizing internal cracks.
Fine Sieve
SAE J444 Grading
Precision screening guarantees every batch meets American SAE-J444 standard.
