Steel Ball
Unidus Hk Cooperation supplies hot‑rolled grinding steel balls made from high carbon chromium alloy steel, with carbon content 0.5‑1.2 % and chromium 0.5‑1.5 %. The balls are offered in diameters from 20 mm up to 150 mm and are hardened to 55‑65 HRC, meeting the GB‑8649‑88 and YB/T 091‑2005 roundness standards. The supplier notes an annual production capacity of 500 000 tons and that the products are exported worldwide, with pricing negotiated per volume, grade and destination.
The high carbon chromium alloy provides a balanced combination of wear resistance and toughness, suitable for intensive milling operations. In the grinding‑media market, typical surface roughness for such balls is Ra ≤ 0.25 µm and roundness tolerance conforms to the referenced Chinese standards. Balls are commonly shipped in bulk metric‑ton containers, with weight per ball varying with size; a 50 mm ball typically weighs about 98 g. The manufacturing process includes hot rolling followed by controlled heat treatment to achieve uniform hardness and low breakage rates.
These grinding balls are used in ball mills for mineral processing, cement grinding and power‑generation fuel preparation, serving mining companies, cement producers and large‑scale power plants. Buyers normally request FOB Shanghai or CIF terms and specify bulk packaging; the supplier highlights a breakage guarantee of less than 1 % under normal operation. Importers should verify the exact diameter, hardness range and packaging details to obtain a formal quotation and arrange freight from the nearest Chinese port.

Sourcing Steel Ball from Unidus Hk Cooperation - China Import Guide
Buyers should request a mill test report showing the carbon and chromium percentages and the achieved hardness, and confirm that roundness complies with GB‑8649‑88 and YB/T 091‑2005. Reviewing the harbor tier verification and any available factory audit photos can help assess reliability. Verify that the declared diameter range matches the size required for your specific mill.
Common incoterms offered are FOB Shanghai or CIF destination; importers must agree on the preferred term before contract. Shipping is usually in bulk metric‑ton containers, and lead time depends on production scheduling and should be confirmed with the supplier. Payment is typically via T/T against pro‑forma invoice, though other terms may be negotiated.
Upon receipt, conduct dimensional checks with a calibrated micrometer to ensure diameter tolerance, and perform a hardness test to verify the 55‑65 HRC range. Request a certificate of compliance and, if required, arrange an independent third‑party inspection before cargo release. Ensure the breakage rate is documented and within the stated < 1 % guarantee.
