Alloy Steel Shot S110/S170/S230 – Versatile Industrial Abrasives
Product Overview
Alloy Steel Shot S110/S170/S230 are high-performance abrasives made from premium alloy steel (C: 0.8-1.2%, Cr: 0.9-1.2%, Mn: 0.6-0.9%) via rigorous heat treatment. Designed for precision surface cleaning, strengthening, and finishing, these shots comply with SAE J444 and ISO 11124 standards. Each grade offers unique particle sizes and hardness levels to meet diverse industrial needs.
Grades & Technical Specifications:
| Grade | Particle Size Range | Hardness (HRC) | Roundness | Density (g/cm³) | Cycle Life (Times) | Typical Applications |
|---|---|---|---|---|---|---|
| S110 | 0.3mm | 40-50 | ≥98% | 7.4 | 2300-2700 | Precision components, electronics, medical devices |
| S170 | 0.5mm | 40-50 | ≥98% | 7.4 | 2330-2700 | Automotive parts, aerospace components |
| S230 | 0.6mm | 40-50 | ≥98% | 7.4 | 2350-2700 | Heavy machinery, steel structures, pipeline cleaning |
Key Features:
Uniform Microstructure: Tempered martensite with fine carbides for balanced hardness and toughness.
Low Fragmentation: ≤5% breakage rate reduces dust and maintenance costs.
High Purity: Sulfur (S) and phosphorus (P) content ≤0.03% to prevent workpiece contamination.
Applications by Grade
S110 (0.3mm, HRC 40-50)
Precision Cleaning:
Electronics: Removing flux residues from PCBs and micro-components.
Medical Devices: Deburring surgical instruments and implant surfaces (Ra ≤3.2μm).
Gentle Strengthening:
Aluminum alloys: Forming 0.1-0.2mm compressive stress layers without surface damage.
S170 (0.5mm, HRC 40-50)
Automotive Industry:
Engine components: Shot peening crankshafts and gears to improve fatigue life by 150%.
Sheet metal: Preparing surfaces for painting with roughness Ra 40-80μm.
Aerospace:
Titanium alloy parts: Cleaning turbine blade roots and fastener holes.
S230 (0.7mm, HRC 40-50)
Heavy-Duty Cleaning:
Steel structures: Removing rust and mill scale from beams and plates (Sa2.5 cleanliness).
Pipelines: Internal blasting of oil/gas pipes to meet API 5L coating standards.
Industrial Equipment:
Refurbishing mining machinery components (e.g., excavator buckets) with deep impact (0.3-0.5mm stress layer).
Process Advantages
Efficient Material Removal:
S230 removes 50μm oxide scale at 200m²/h, 30% faster than regular steel shot.
Cost-Effective:
Long cycle life reduces replacement frequency; S230 costs 20% less than imported equivalents over 10,000 cycles.
Customization Options:
Mixed grades (e.g., S170 + S230) for gradient blasting to optimize efficiency and surface finish.
Anti-static and heat-resistant coatings available for special environments.
Quality Assurance
ISO 9001 Certified: Each batch undergoes strict testing for hardness, size distribution, and chemical composition.
Traceability: Full material origin and heat treatment records provided upon request.
Packaging & Logistics
Standard Packaging: 25kg/bag (polypropylene), 1 ton/pallet (stretch-wrapped for moisture protection).
Lead Times: 3-5 days for standard orders, 7-10 days for customized specifications.
Why Choose S110/S170/S230?
Versatility: Three grades cover 80% of industrial blasting needs, from micro-precision to heavy-duty applications.
Performance Consistency: Tight control over particle size and hardness ensures uniform results across batches.
Environmental Compliance: 100% recyclable and RoHS/REACH compliant for sustainable operations.
