The product is a miniature stainless‑steel ball manufactured in SUS440C, a high‑carbon martensitic alloy containing 0.95‑1.20 % carbon, 16‑18 % chromium and up to 0.75 % molybdenum. Diameter options run from 2.0 mm to 25.4 mm and are offered in precision grades ranging from G10 to G500. Hardness is specified between HRC 58 and HRC 65, meeting the AFMBA grade standard and DIN 5401. The supplier lists ISO 9001‑2008, ISO 14001 and TS‑16949 certificates for the production line.
SUS440C provides superior corrosion resistance compared with ordinary AISI 420 steel, making the balls suitable for environments containing fresh water, steam, oil or food‑grade media. Typical industry practice limits sphericity deviation to ±0.001 mm and surface roughness to Ra 0.2 µm for bearing‑grade applications. The balls are supplied in bulk paper or poly bags, each bag holding up to 5 kg of product.
Automotive manufacturers, hydraulic system builders and precision grinder producers commonly source these balls for bearing assemblies and wear‑resistant components. Packaging complies with international export requirements, and the supplier can provide test certificates on request. Prospective buyers should verify the exact minimum order quantity, lead time and chosen Incoterm directly with the supplier before placing an order.

Before confirming an order, buyers should request the material test report to verify the SUS440C composition, confirm the exact grade tolerance required for their application, and ask for the supplier’s latest ISO and TS certificates. It is also advisable to clarify the minimum order quantity and any special packaging requests to avoid unexpected freight costs.
The balls are shipped from ports in Guangdong province; typical Incoterms offered include FOB or CIF, but the exact term must be agreed with the supplier. Payment methods such as T/T or LC are common in this trade, and buyers should confirm the preferred method and any advance payment requirements before finalising the contract.
Quality assurance normally involves third‑party inspection of hardness, dimensional accuracy and surface finish. The supplier can provide a mill test certificate and, if required, an independent inspection report from an accredited lab. Maintaining records of these documents helps streamline customs clearance and ensures compliance with the buyer’s quality standards.
