Across mountains and seas, let's talk about cooperation! An important African client visited the Haoyang factory for an on-site inspection.

Jinan Haoyang Casting and Forging has seized the global opportunities in mineral development. Its forged steel balls that comply with YB/T 091 standards have entered international mineral projects in countries such as the Democratic Republic of the Congo and Chile. The products cover specifications ranging from Φ70mm to Φ200mm, are compatible with various grinding equipment, and can be supplied in single batches of over 1,000 tons. The company has set up 3 service stations overseas. In 2025, overseas orders will increase by 52%, and the share in the new energy mineral sector will exceed 40%, helping to achieve efficient global resource development.

✅ Medium‑impact 45# carbon steel，Optimized for cement plant & sand‑making mill working condition ✅ Stable HRC48‑55 hardness，Uniform hardness distribution, less peeling in continuous grinding ✅ Low breakage rate ≤1%，Reduce mill unexpected shutdown and maintenance cost ✅ Hot‑forged from solid round steel，No scrap remelting, stable metallographic structure ✅ Cost‑effective grinding media，Lower comprehensive consumption for medium‑hard material grinding ✅ Batch‑by‑batch inspection，Chemical & hardness test reports available for every shipment ✅ Flexible packaging solution：ton‑bag / steel drum on wooden pallet for sea container shipment

✅ Uniform Hardness Distribution：Surface HRC55‑65, stable core hardness, no easy peeling. ✅ Low Breakage Rate：Breakage rate ≤1%, avoid mill block‑down caused by broken balls. ✅ High Impact Toughness：Impact value ≥12 J/cm², fit heavy‑load SAG mill & large ball mill. ✅ Long Service Life：Dense metallographic structure, lower wear consumption than cast grinding balls. ✅ Strict Quality Control：100‑percent hardness & dimension inspection per batch, SGS test report available. ✅ Customizable：Multiple grades & sizes to match different ore hardness and working conditions
