As Indonesia’s premier stainless steel ball manufacturer, Changzhou Feige Steel Ball Co., Ltd. combines advanced production technology with comprehensive export capabilities to serve global industrial markets. With an annual production capacity of 4,000 tons across our 18,000㎡ main and branch factories, we specialize in manufacturing precision stainless steel balls ranging from 0.3mm to 100mm in diameter, covering all precision grades from G3 to G2000. Our “Saige” brand stainless steel balls have earned international recognition through ISO9001, IATF16949, ISO14001, and ISO45001 certifications, making us the preferred supplier for demanding industrial applications worldwide.
Precision Stainless Steel Ball Production Capabilities
Our state-of-the-art manufacturing facilities in Indonesia are equipped with advanced cold heading machines, precision grinding lines, and automated inspection systems that ensure consistent quality across all production batches. The manufacturing process begins with carefully selected raw materials that meet AISI 304/316/420/440C standards, followed by cold heading forming, rough grinding, heat treatment, fine grinding, and lapping processes. Each stainless steel ball undergoes rigorous quality control including dimensional inspection, surface roughness measurement, hardness testing, and roundness verification using sophisticated equipment like laser micrometers and roundness testers.
The precision grading system we implement ranges from G3 (highest precision) to G2000 (standard commercial grade), enabling us to serve diverse applications: G3-G10 for high-precision bearings and measuring instruments, G16-G100 for automotive components and industrial machinery, and G1000-G2000 for general engineering purposes. Our dimensional capabilities cover the complete spectrum from miniature 0.3mm balls for medical devices to large 100mm balls for heavy machinery applications.
Custom Stainless Steel Ball Solutions
Understanding that standard products often cannot meet specialized industrial requirements, we offer comprehensive customization services through our Indonesian manufacturing base. Our engineering team works closely with clients to develop tailored solutions for unique applications, including:
- Material Customization: Beyond standard stainless steel grades, we provide specialized alloys like 17-4PH, 15-5PH, and duplex stainless steels for enhanced corrosion resistance or mechanical properties
- Dimensional Precision: Tight tolerance manufacturing down to ±0.001mm for critical applications in aerospace and semiconductor industries
- Surface Treatments:
- Passivation for improved corrosion resistance
- Electropolishing for ultra-smooth surfaces

FAQ
What is the minimum order quantity for custom stainless steel balls?
Our minimum order quantity starts from 10,000 pieces for standard sizes and 5,000 pieces for custom dimensions, depending on the complexity of specifications. For prototype development or small-batch production, we offer special arrangements through our rapid manufacturing service with slightly higher unit pricing.
How do you ensure quality consistency across large production batches?
We implement comprehensive quality control systems including Statistical Process Control (SPC) for critical manufacturing parameters, 100% dimensional inspection using laser measurement systems, and regular material analysis through spectrometers. Each production batch is accompanied by detailed quality reports documenting all inspection results.
What lead time should be expected for stainless steel ball orders?
Standard product orders typically ship within 15-20 working days after order confirmation. Custom orders require 25-35 working days depending on specification complexity and production scheduling. For urgent requirements, we offer expedited processing with priority production scheduling for an additional fee.
Can you provide stainless steel balls with special surface coatings?
Yes, we offer multiple surface treatment options including passivation for improved corrosion resistance, electropolishing for ultra-smooth surfaces, black oxide coating for reduced light reflection, and various PVD/CVD coatings for enhanced wear resistance. Our engineering team can recommend the most suitable coating based on your specific application requirements.
What certification documents are provided with each shipment?
Every shipment includes comprehensive documentation package containing: ISO9001 quality certificate, IATF16949 automotive certification (if applicable), material test report (MTR), dimensional inspection report, surface roughness certificate, and hardness test results. For food-grade or medical applications, we provide additional certification documents as required.
