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%.
