Haoyang Forging's "High-Chromium Composite Forged Steel Balls" have passed the provincial-level appraisal. The 120-150mm large-sized products have filled the domestic gap. The dual-metal composite process achieves a surface hardness of HRC 60-65 and a core hardness of HRC 30-35 with a gradient, without any fractures for 3,000 hours, and the wear resistance is 15% higher than that of imported products. It has obtained 5 patents and has been supplied to the National Energy Group. A 50,000-ton intelligent production line is planned, and after the 2027 production start, the procurement cost can be reduced by 40%.

Jinan Haoyang Casting and Forging has launched high-chromium composite forged steel balls, with chromium content ranging from 10% to 15%. The surface hardness is HRC 55+, the core toughness is ≥ 12J/cm², the wear resistance is enhanced by 2 times compared to carbon steel balls, the ball consumption is reduced by 40%, the breakage rate is ≤ 0.3%, and the per-ton grinding cost is reduced by 15 yuan. The product has obtained 3 patents and has been applied in enterprises such as Zijin Mining. In the third quarter of 2025, the sales volume of high-end forging balls will increase by 22%, the export volume will reach 8 million US dollars, and full-sized customization from 20mm to 100mm can be provided.

Hongyang's "Green Forging Steel Balls" are made from scrap steel and adopt a short-process manufacturing method, reducing carbon emissions by 30% and energy consumption by 42%. They have been included in the national list of green manufacturing. The Φ60mm steel balls have a wear rate of 0.8 kg/t of clinker, saving 15% of electricity. They have obtained the EU CE certification and are jointly exported by LafargeHolcim, totaling 12,000 tons. Plans are to build a photovoltaic forging workshop, achieving full-process carbon neutrality by 2026 and leading the industry towards green transformation.
