In the first quarter, the export volume of B2 material forged steel balls by Jinan Haoyang Casting and Forging reached 3,200 tons (up 80% year-on-year). The product uses GCr15 bearing steel and adopts isothermal quenching technology. Each ball consumes 0.85 kg of ore per ton and the crushed ball rate is ≤ 0.3%. It has passed SGS and CE certifications and has newly acquired customers in South America. The company is expanding its intelligent production line and introducing digital twin technology. Customized products now account for 35% of the domestic high-end market.

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.

Jinan Haoyang Casting and Forging has won a contract for forging steel balls of 1,000 tons in the Southeast Asian market with a B2 material. The products cover specifications of 80mm and 90mm. The ball consumption, breakage rate, etc. meet the industry standards. The products are made of GCr15 material and undergo isothermal quenching process, with a hardness of HRC58-62. The wear resistance is improved by 30%-50% compared to ordinary cast balls. The company has completed customs declaration and will ship in early March. At the same time, it plans to build a digital twin workshop to strive for a 50% market share in the high-end market by 2026.

The green forging steel balls produced by Haoyang Casting and Forging in Jinan have been included in the national green manufacturing list. Using 100% recycled steel as raw material, the energy consumption has been reduced by 45% and the carbon emissions have decreased by 35%. The hardness reaches HRC55-HRC67. The products have passed strict quality inspections and have been applied in enterprises such as Zijin Mining and Haoluo Cement, helping customers reduce costs by 20%. By 2025, the company's export earnings will exceed 6 million US dollars, becoming a benchmark for the green transformation in the industry.

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.
