Our “Saige” brand stainless steel balls are exported to over 30 countries worldwide, serving clients in Europe, North America, Southeast Asia, and the Middle East.
Product Range: Full-Spectrum Stainless Steel Ball Solutions
Our product portfolio covers the complete spectrum of stainless steel ball requirements:
1. Standard Product Series
We manufacture stainless steel balls in sizes ranging from 0.3mm (micro precision) to 100mm (heavy-duty) with precision grades from G3 (highest precision) to G2000 (general industrial). All standard products comply with international standards including AISI 304/316/420/440C, GCr15, and other specialized stainless steel grades.
| Parameter | Specification |
|---|---|
| Diameter Range | 0.3mm – 100mm |
| Precision Grades | G3, G5, G10, G16, G20, G28, G40, G60, G100, G200, G500, G1000, G2000 |
| Material Grades | 304, 316, 420, 440C, GCr15, 9Cr18Mo, etc. |
| Surface Finish | Polished, ground, passivated, black oxide, etc. |
2. Custom Manufacturing Capabilities
What truly distinguishes us is our ability to create bespoke stainless steel ball solutions. Our engineering team works closely with clients to develop:
- Non-standard sizes (special diameters beyond standard range)
- Complex shapes (flat, oval, truncated, threaded, etc.)
- Special material compositions (corrosion-resistant alloys, magnetic grades)
- Precision surface treatments (electroplating, PVD coating, laser marking)
- Tight tolerance requirements (down to ±0.001mm for critical applications)
Our custom manufacturing process follows a rigorous 8-step protocol: material analysis → CAD design → prototype production → performance testing → mass production → quality inspection → packaging customization → logistics coordination. This ensures every custom order meets the exact specifications and performance requirements.
Quality Control: The Foundation of Our Reputation
At Changzhou Feige, quality isn’t just a department – it’s embedded in every production stage through our comprehensive Quality Management System (QMS). Key quality control measures include:
1. Raw Material Verification
All incoming stainless steel materials undergo strict verification using spectrometers, hardness testers, and corrosion resistance testing equipment. We maintain material traceability records for every production batch.
2. In-Process Inspection
During production, we implement 100% inspection at critical points using:
- Laser diameter measurement systems (±0.0005mm accuracy)
- Roundness testers (0.05μm resolution)
- Surface roughness analyzers
- Salt spray test chambers for corrosion resistance evaluation
3. Final Product Certification
Every stainless steel ball leaving our factory comes with:
- Material composition certificate
- Dimension inspection report
- Surface finish verification
- Batch traceability code
- Optional third-party inspection reports (SGS, TÜV, etc.)

FAQ
What’s the minimum order quantity for custom stainless steel balls?
Our MOQ varies based on complexity: 5,000 pcs for standard sizes, 10,000 pcs for simple custom shapes, and 20,000 pcs for complex custom designs. We evaluate each custom order individually to provide flexible solutions.
How do you ensure consistency in large production batches?
We implement statistical process control (SPC) throughout production, with real-time monitoring of key parameters. Our automated grinding machines maintain ±0.001mm consistency across batches, and we conduct random sampling from every production lot for verification.
What’s your typical lead time for standard products?
For stock items, we can ship within 7-10 working days. For standard non-stock sizes, production takes 15-20 days. Custom orders require 25-40 days depending on complexity, with rush options available for urgent requirements.
Can you provide material certificates for each batch?
Absolutely. Every shipment includes a comprehensive material certificate showing chemical composition analysis, mechanical property test results, and heat treatment records. We can also arrange third-party inspection reports from SGS, TÜV, or other accredited laboratories upon request.
What payment terms do you accept for international orders?
We offer flexible payment options: 30% advance with balance against BL copy for first-time buyers, and net 30 days for established clients with credit approval. We accept T/T, LC at sight, and PayPal for sample orders.
