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.

Jinan Haoyang Forging & Casting Co., Ltd. was established in 2011, specializing in the production of castings and forgings. Its hot-rolled grinding balls are made of B2/B3 materials and are suitable for the mineral processing fields such as mines and cement plants. The products are characterized by their resistance to abrasion and impact, with specifications ranging from 20 to 160mm, meeting diverse demands. It has achieved certain transaction volume on the Alibaba platform, and has a promising market outlook. The company continuously optimizes product performance based on a scientific quality management system. As the demand in the mining and cement industries expands, it is expected to further increase its market share and promote technological upgrading in the industry.
