About Shandong Iraeta Heavy Industry Stock Co., Ltd. - Steel Balls Supplier in China

China's Shandong province hosts Shandong Iraeta Heavy Industry Stock Co., Ltd., which currently lists six active products in its catalogue. The supplier categorises its offerings under Steel Balls and Agriculture, although the present product list focuses on grinding media used in mineral processing, cement grinding and other industrial applications.

The catalogue includes forged and cast grinding steel balls, a generic grinding ball entry (HS code 7326.11, material high carbon steel forged or hot rolled), a cast grinding steel ball (HS code 7325.91, high‑carbon chromium alloy steel with 0.7‑2.3 % C and 0.3‑2.0 % Cr), low‑price forged solid steel balls (HS code 7325.91, high‑carbon low‑alloy forged steel) and a high‑chrome casting and forged grinding ball. Each entry references the relevant HS‑code families for steel balls (7325 and 7326) and specifies the primary material composition.

Product Range and Specialties of Shandong Iraeta Heavy Industry Stock Co., Ltd.

The six listed items cover both forged and cast grinding steel balls, ranging from high‑carbon steel to high‑chrome alloy formulations. In the grinding media market, forged balls typically meet ISO 4923 specifications with hardness of 62‑66 HRC, diameter tolerances of ±0.02 mm for sizes up to 30 mm, and surface roughness Ra ≤ 0.8 µm. Cast balls often conform to ASTM A295, featuring a chromium content of 0.3‑2.0 % and carbon levels of 0.7‑2.3 % to improve wear resistance. Buyers also encounter standard size series (e.g., 5 mm, 10 mm, 15 mm, 20 mm, 30 mm) and weight grades such as 5 kg, 10 kg or 20 kg per bag, packed in wooden crates for container loading.

Trade and Export Information - Shandong Iraeta Heavy Industry Stock Co., Ltd.

China is a major exporter of grinding media, with shipments routinely directed to mining regions in Africa, the Middle East, and South‑America, as well as to cement and steel producers in Southeast Asia and Europe. The HS code 7325.91 applies to cast steel balls, while 7326.11 covers forged steel balls and other grinding media; customs authorities often require a mill test report and a certificate of origin for these codes. Typical buyer requirements include ISO 9001 quality management certification, SGS or Bureau Veritas inspection reports, and compliance with local environmental or safety standards such as REACH for metal content. Export logistics favour 20‑ft or 40‑ft containers, with balls packed in wooden pallets or bulk bags, and trade terms commonly cited as FOB Shanghai or CIF destination port.

Sourcing from Shandong Iraeta Heavy Industry Stock Co., Ltd. - Buyer Guidance

When sourcing grinding balls from this supplier, request a detailed mill test report that lists chemical composition, carbon and chromium percentages, and hardness values. Verify whether the balls are forged or cast, as forged media provide higher impact strength while cast media offer better wear resistance for abrasive ores. Ask for ISO 4923 or ASTM A295 certification copies, and confirm packaging dimensions to ensure compatibility with container loading plans. Sampling a representative size batch before a full order helps validate size tolerance, surface finish and material consistency.

What HS codes are associated with the grinding steel balls listed by the supplier?

The forged grinding steel balls fall under HS code 7326.11, while the cast and low‑price forged solid balls are classified under HS code 7325.91, which covers cast steel balls and related grinding media.

Which material grades are used for the supplier's grinding balls?

Materials include high‑carbon steel (forged or hot rolled), high‑carbon low‑alloy forged steel, and high‑carbon chromium alloy steel containing 0.7‑2.3 % carbon and 0.3‑2.0 % chromium.

What typical size range can buyers expect for these grinding balls?

Industry practice for grinding media covers diameters from 5 mm up to 30 mm, with standard weight grades of 5 kg, 10 kg or 20 kg per bag, which align with the supplier’s product line.

Which certifications should a buyer request for grinding steel balls from China?

Buyers should request ISO 9001 quality management certification, a mill test report, and any third‑party inspection report (e.g., SGS, BV) that confirms chemical composition and hardness.

What packaging and shipping format is commonly used for these products?

Grinding balls are typically packed in bulk bags or wooden crates, loaded on standard 20‑ft or 40‑ft containers, and shipped under FOB or CIF terms.

What industries most frequently import grinding steel balls from China?

The primary importers are mineral‑processing mines, cement factories, steel mills, and chemical plants that require fine grinding media for grinding mills.

How can a buyer verify the quality of forged versus cast grinding balls?

Ask for separate test reports that detail hardness (62‑66 HRC for forged, 58‑62 HRC for cast), impact resistance, and micro‑structural analysis; forged balls generally show higher impact strength.

What lead time is typical for orders of grinding steel balls from this supplier?

Lead times for forged or cast grinding balls from Chinese manufacturers usually range from 30 to 45 days after receipt of a confirmed purchase order and required documentation.
