What is Steel Shot?
Steel shot is a spherical metallic abrasive produced through the atomization of molten high-carbon or alloy steel. SEPPE Steel Shot is engineered for durability and performance with industry-leading specifications:
Hardness: HRC 40-46
Density: ≥7.4 g/cm³
Roundness: ≥95%
These precision-controlled properties ensure maximum impact energy transfer and an exceptionally long service life.
Key Applications of Steel Shot
1. Shot Peening (Fatigue Resistance)
Strengthen critical components like automotive gears, crankshafts, and aircraft blades. The high-speed impact creates a compressive stress layer, significantly extending the fatigue life of parts and preventing surface cracks.
2. Surface Cleaning & Descaling
Efficiently remove scale, molding sand, and welding slag from castings and forgings.
Sa 2.5 Finish: Achieve a clean, smooth surface free of burrs.
Equipment Friendly: The spherical shape reduces wear on blast machine liners compared to angular grits.
3. Surface Finishing
Ideal for deburring precision machined or stamped parts. Steel shot delivers a uniform matte finish and provides an optimal profile for superior coating and plating adhesion without altering part dimensions.
Why Choose Steel Shot? (Core Advantages)
Cost-Efficiency: Can be recycled and reused thousands of times, drastically lowering your abrasive consumption.
Low Dust: Produces minimal dust for a cleaner workspace and better visibility during operation.
Uniform Impact: Spherical particles ensure an even surface texture without deep scratching.
Maintenance Tip: To maintain peak efficiency, add new shot regularly to maintain the "working mix," screen out fines/dust, and ensure workpieces are pre-cleaned to avoid contamination.
Steel Shot Size Selection Guide
Choosing the right size depends on your specific surface requirements. SEPPE offers a full range from S170 to S460:
Size range | Impact Level | Best for |
S170/S230 (fine) | Gentle | Thin-walled parts, aluminum, and precision components.
|
S280/S330 (medium) | Balanced | The Industry Standard. Ideal for carbon steel castings and structural parts.
|
S390/S460 (Coarse) | High | Heavy forgings and removing thick heat-treat scale.
|
If you are unsure, start with S330. It offers the best balance of cleaning speed and surface quality for most industrial applications.
Whether you need to strengthen metal parts, clean heavy castings, or achieve a flawless matte finish, SEPPE Steel Shot is the high-performance, low-dust solution.
