Innovative forged steel ball technology leads the upgrading of the grinding medium industry
Jinan Haoyang Forging & Casting Co., Ltd. (hereinafter referred to as "Haoyang Forging & Casting") has announced the launch of a new generation of high-maintenance cast and forged steel ball series products. Through the integrated process of "forging + heat treatment", the service life of these products has been increased by more than 30%, breaking the industry pain point of traditional grinding media being prone to wear and frequent replacement. This series of products covers diameters ranging from 20mm to 150mm in all specifications. It has passed SGS hardness testing (surface hardness 58-62 HRC) and impact toughness tests (≥12J/cm²), and its performance has reached the international advanced level.
As a specialized, innovative, distinctive and high-quality enterprise in Shandong Province, Haoyang Casting and Forging has been deeply engaged in the field of casting and forging for 15 years. It has 6 automated production lines with an annual production capacity of 20,000 tons. This new product is made of 42CrMo alloy material and uses medium-frequency induction heating technology. Through a three-stage process of "forging - isothermal quenching - low-temperature tempering", it achieves grain refinement and uniform hardness control. It is particularly suitable for high-strength grinding scenarios in mining, building materials, and metallurgy. "Our steel balls, in a certain large-scale gold mine's wet grinding process, have a single consumption of 0.8 kg/t of raw ore, which is 25% lower than that of similar products," said Mr. Wang, the technical director of the company.
Currently, Haoyang Forging has established partnerships with companies such as BHP Billiton of Australia and copper mining companies from Chile, and the proportion of its products exported has reached 40%. In the first half of 2025, the company's revenue increased by 18% year-on-year, and the proportion of R&D investment rose to 6.5%. It has successively received titles such as "Leading Enterprise in the Casting Industry of Shandong Province" and "Green Factory". In the future, the company plans to invest 50 million yuan to build an intelligent workshop, introducing industrial robots and digital twin systems. The goal is to increase the market share of high-end products to 60% within three years.
