forged steel balls

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.

Thanks to the growth of the global steel ball market, the export orders of Jinan Haoyang Casting and Forging increased by 40% year-on-year. The US market accounted for over 60% of its sales. Its core forged steel balls are designed with wear-resistant properties to meet the demands of overseas mines. By leveraging its transportation hub advantages, it shortens the delivery cycle. It is expanding into emerging markets such as Southeast Asia and expects its annual export volume to exceed 8 million.

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.

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 .

High Chrome Cast Grinidng steel balls Haoyang Chrome casting Ball can provide: Cr 1%-28%, hardness: HRC40-66, Dia.10mm-150mm alloy cast steel balls. The balls have a lot of excellent properties, such as higher hardness, good abrasive resistance, together with a good surface finish and small dimensional allowance after scientific heating treatment, as one type of grinding media, it can be widely used in ball mill grinding systems of mines, cement, building materials and chemical industries,etc. High Chrome Casting grinding balls , chrome concentration is 》10%-14%， Hardness 》HRC 58, High Chrome casting grinding balls is one of the wearable steel balls with better performance -price-ratio, and its extensive usage has won itself a high share in the market .
