Ultra Fine Steel Shot
Ultra Fine Steel Shot is a super-fine particle blasting medium developed by LuXing Metal for precision surface treatment
1 / 7Technical Overview
Ultra Fine Steel Shot UFSS | Super-fine blasting medium, particle size 0.1-0.7mm, high-carbon steel spherical abrasive. For precision shot peening, micro-deburring & ultra-precision surface finishing. Low RA, safe for thin-walled parts, penetrates micro-holes & narrow gaps. First choice to replace glass beads & non-metallic abrasives.
Ultra Fine Steel Shot is a super-fine particle blasting medium developed by LuXing Metal for precision surface treatment. Made from premium high-carbon steel via advanced atomization, it delivers excellent sphericity, uniform particle distribution, and soft impact characteristics. Compared to standard steel shot, ultra fine shot features significantly smaller diameters (0.1–0.7 mm), enabling deep penetration into micro-holes, narrow gaps, and complex internal cavities — making it irreplaceable in precision component processing.

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.
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.
