It has obtained the EU CE certification and is expected to export 3,000 tons per year. Plans to add 2 more nuclear power production lines.

In 2026, Haoyang Casting and Forging of Jinan will launch gradient hardness forged steel balls. Using the "double-frequency quenching" process, the surface hardness reaches 65HRC while the core has a toughness of 15J/cm², resulting in a 50% increase in wear resistance and a 40% improvement in mining grinding efficiency. This technology has obtained a national patent and has been supplied in batches to enterprises such as Zijin Mining and exported overseas. The company plans to invest 20 million yuan to expand the production line, with a target annual production capacity of 30,000 tons, aiming to occupy 30% of the domestic high-end market share.

The new generation of gradient hardness forged steel balls developed by Jinan Zhangqiu Huayi Heavy Industry Co., Ltd. have achieved a 40% increase in product lifespan through the "multi-stage forging + zone quenching" process, and their wear resistance exceeds the EU standards by 12%. After testing, the surface hardness is 60-64 HRC, the impact toughness is ≥ 15 J/cm², and the industrial test single consumption is 0.52 kg/t of raw ore, which is 32% lower than that of imported products. Currently, the annual production capacity is 30,000 tons, and it supplies leading mining enterprises at home and abroad. In the third quarter of 2025, the high-end sales volume will increase by 58%, helping the Zhangqiu forging industrial cluster's output value exceed 8 billion yuan.

Recently, Jinan Haoyang Casting and Forging Co., Ltd. (hereinafter referred to as "Haoyang Casting and Forging") has launched a new generation of high-performance forged balls. Through the integrated process of "forging + isothermal quenching", the service life of the products has been increased by 35%, and the wear resistance has exceeded that of traditional cast balls by more than 15%. This has attracted widespread attention from the mining and construction industries. This series of forged balls covers a full range of specifications from 20mm to 150mm. After being tested by the National Quality Supervision and Inspection Center for Casting and Forging Machinery, the surface hardness reaches 58-62 HRC, the impact toughness is ≥ 12J/cm², and the comprehensive performance has reached the international advanced level.

Jinan Haoyang Casting and Forging has built the first low-carbon casting and forging steel ball production line in China. The energy consumption per ton of steel is 320 kilograms of standard coal, which is 28% lower than the industry average. It reduces carbon emissions by 5,600 tons annually and has been awarded the title of "Shandong Province Green Factory". Through technologies such as natural gas heating and steel slag recycling, the utilization rate of raw materials reaches 98%. The proportion of green products exported is 45%. In the first half of 2025, the company's revenue increased by 19%. The company has established a carbon footprint traceability system and plans to achieve 100% clean energy substitution within three years, creating a "zero-carbon forging" base.

Jinan Haoyang Casting and Forging Co., Ltd. has launched a new generation of high-maintenance cast and forged steel balls. Through the "forging + heat treatment" process, the product lifespan has been increased by 30%. The diameters range from 20mm to 150mm, with a hardness of 58-62 HRC and an impact toughness of ≥ 12J/cm². As a specialized, innovative and high-quality enterprise with an annual production capacity of 20,000 tons, its products have been exported to countries such as Australia and Chile. In the first half of 2025, the revenue has increased by 18%. The company plans to invest 50 million yuan to build an intelligent workshop, with the goal of achieving a high-end market share of over 60% within three years.

The "gradient hardening forging steel ball" developed by Haoyang Casting and Forging in Jinan has achieved a significant breakthrough: the wear resistance and service life have been increased by 80%, and the surface hardness reaches HRC 62-65. It adopts the "double-frequency induction quenching + digital twin production" technology, with a raw material utilization rate of 95% and a tonnage steel energy consumption reduction of 18%. This product has broken the dependence on imports, outperforming international brands in terms of performance. It has received 5,000 tons of orders and has increased annual output value by 120 million yuan. The enterprise has jointly established a laboratory with Shandong University to promote the transformation of traditional forging industry towards intelligence and greenness, and to assist Zhangqiu in building a wear-resistant material industrial cluster.

The data quality inspector of the government office went to global steel ball suppliers. Jinan Haoyang Casting and Forging achieved a turnaround by adopting a data-driven model: an export map covering 23 countries, a 300% increase in revenue, and UN procurement qualifications. Its original "steel ball digital ID" system, integrating data quality inspection experience from the government office and industrial 4.0 technology, enables each steel ball to be traced through 38 processes. The green forging standards it led in formulating will drive a 40% reduction in industry carbon emissions.

The third-generation forging steel balls developed by Jinan Haoyang Casting and Forging have achieved the "double crown record" of a hardness of 65HRC and a toughness of 25J/cm². Their lifespan has been increased by 200% compared to traditional products, and they have received a 500-ton order from BHP Billiton. This product adopts an aerospace-grade heat treatment process and has been verified through 2,000 impact tests. In mining applications, it can reduce material costs by 30%. It has obtained 3 invention patents and marks that China's forging steel ball technology has entered the first echelon of the global industry.
