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.

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.
