"Steel Ball Hardness Ceiling" - New Wear-resistant Material Increases Lifespan by 200%
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.
