forged steel ball

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 .

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.
