steel balls

In January 2026, Haoyang Casting and Forging of Jinan launched gradient-hardening forged steel balls. The surface hardness is 65HRC, the toughness is 18J/cm², and the lifespan has been increased by 40%. The unit consumption is 0.5kg/t of raw ore. Using the 42CrMoV alloy and medium-frequency heating technology, it obtained a national patent. The first batch of 2,000 tons of orders will be supplied to BHP Billiton. The annual production capacity is 30,000 tons. A digital twin workshop is planned to be built, with the goal of achieving a 40% market share in the high-end market.

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.

✅ 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

Raw material Quality Control : The forged grinding balls ' steel rods are purchased from the famous steel company in China ( 50,000 Tons annually ). It will be strictly inspected before into the warehouse. Production Line : Forged grinding balls mainly use Automatic rolling machine for 20mm to 70mm balls . Above 70mm to 150 mm , we will use the labor forging hammer , which will increase the grinding balls intensity and tougness . We have special department of QC teamwork .The QC department director have 10 years experience in this industry . The team is responsible for inspection during production , inspection before delivery. ( Grinding balls Surface and core hardness test each day each batch and all will be recorded and filed in documents ).

CADI Grinding balls or ADI grinding Balls 1. High Hardness and good wear resistance 2. Hard Outside and Tough inside , not broken 3. Regular appearance and increased production 4. Light weight and obvious energy saving effect The ADI grinding balls life is ordinary low chromium grinding balls with the operating conditions of 2-3 times is 1-1.5 times of high chrome casting balls and forging balls , save grinding mechanical and electrical consumption of 10-15% increase the output capacity more than 5% , reduce 5nb noise , impact toughness ak=12-21j/cm2, is an ideal grinding balls for large ball mill and SAG in the future .
