About Forged Ball:
Forged ball is a steel ball produced by forging process
The production process of forged ball mainly includes air hammer forging and rotary cutting and rolling.
Features of forged ball
Material: Forged ball uses high-quality raw steel as material
Impact toughness: The impact toughness of forged ball is greater than 12 joules
Breakage rate: The breakage rate of forged ball is less than 0.5%
Surface quality: The surface of forged ball is smooth, without pouring mouth, sand hole and ring band
Hardness: The surface hardness of forged ball is between HRC56-HRC65, the core hardness is between HRC54-62, and the overall hardness is high and uniform Wear resistance: The wear resistance of forged ball is better than that of cast ball, and the service life is longer, which can reduce the use cost and improve the enterprise efficiency.
